How to do #21 In Your Number of the Day Book.





Goal: Use any two digits to make a PROPER fraction.

There are two numbers in a fraction, the top # is called the NUMERATOR and the one at the bottom is called the DENOMINATOR.

To make a proper fraction, you must make the numerator smaller than the denominator.

The image on the left displays an example of how a proper fraction should look like.

The image on the right displays MIXED and Improper. Those 2 fractions on the image at the right is NOT a proper fraction.

Hope this helps,

Matt.

How to do #23 in the number of the day booklet

23. Write the answer to number 21 as a decimal

All you are doing is changing a proper fraction to a decimal

Decimals are always over 1

Whatever you do to the top number you have to do to the bottom number
Example if your proper fraction was one half:

How To Do #20 In The Number Of The Day Booklet

20. Write a fraction using the 1000s place as the denominator and the tenths place as as the numerator.

Take the number in the 1000s place and put it as the Denominator then take the number in the tenths place and put it as the numerator ( or do it the other way around).

example: 4567.892
8/4= Improper Fraction (Top is greater than the bottom)
8- Numerator: Top Number
4- Denominator: Bottom Number

it says use a calculator.. but.. oh well.. :P lets do this mentally!... most of it mentally..

a) 13/25 <-- lets pretend it looks like this13

25


so for "a)" we need to round it to tenths! if we're going to turn fractions to decimals...

what are decimals??


~Quick lesson~

Decimals are always over one..

eg. _ /1

one is your denominator

~~~~~~~

so, lets start^^

if 25 is our denominator, how much do we have to divide it by to get one? ... you know the answer....

so divide 25 by 25 and you'll get 1. and what ever you do to the bottom you'll have to do it to the top. 13 divided by 25 is 0.5200 (what it says on my calculator)

round 0.5200 by tenths = o.5


so our answer is 0.5/1

Lets do the rest now! :D

b) 107/215 . 215 divided by 215 = 1 . 107 divided by 215 = 0.4976 (like how it says on the calculator again) 0.4976 round it off by hundredths = 0.50 . our answer is 0.50/1

c) 43/50 . 50 divided by 50 = 1. 43 divided by 50 = 0.860. 0.860 round it by tenths = 0.9

so our answer is 0.9/1

d) 197/289 . 289 divided by 289 = 1 . 197 divided by 289 = 0.6817. 0.6817 round it by thousandths = o.680. so our answer is o.680/1


Hope you learned at least something :)

for A you only have to put the bar notation 4 because that was the only number that was repeating.

for B you have to do that because you only put the bar notation on the #'s that are repeating, because 2 never repeated so then you don't put the bar notation on 2 only on the 6.

for C you have to put the bar notation on 185 why? well because 185185... is repeating so since they all are repeating you have to put the bar notation on 185.

for D you have to put it on only 62 because the 0 isn't repeating and because both 6 and 2 are repeating so you have to put the bar notation on both of them.

whole numer



Eg. 1/2, 3/4/, 5/3



Decimals



Anything



over



1



EG 0.1/1, 0.5/1, 0.375/1



Percents



Percent is out of 100%



9/10 = 90%



Converting means changing fractions to decimals





2/3 = 0.75/1



0.75 is a terminating number





0.66 = repeated decimal, 0.6666666666666666666666666666 never ends



















Converting Fractions and Decimals

Fractions are: Decimals are: Percents are:
whole numbers anything anything
whole numbers 1 100
e.g. 1, 3, 5, etc. e.g. 0.1, 0.5, 0.375 e.g. 60% = 60, 54.7%=54.7
2 4 3 1 1 1 100 100
Not 30%, 0.1 or 0.5 e.g. 6 = 6 = 6.0
3 1

Convert means change

e.g. Fractions to Decimals

1 = 0.5
2 1

Convert 3 to a decimal:
4

3 = .75
4 1 o.75 is a Terminating decimal

Convert 2 to a decimal:
3

2 = .6666.....
3 1 0.666666.........is a repeating decimal, another way to write this is:
_
0.6 (the line is supposed to be above the six)

Finding the Percent of a Number

Hello, I am going to show you how to find the percent of a number.

An example of a question would be like - 25% of 80 is ? Now to find the percent of a number, you must use a Ratio Table. The ratio table must look like a T-chart:

Example (this is not what it should look like):
(Percents will be below this)-->%<-------------->#<--(Numbers will be below this.)

Now to figure out the answer of the question:

1. You make a T-chart and on the % side, you write 100:

%<-------------->#
100

2. On the # side you write the number, for this question, it is 80:

%<-------------->#
100 80

3.to reach 25% you should start the easy way - divide 100 by 2 = 50%:

%--------------#
100-----------80
50------------

4. Do what you did on the percent side:

%--------------#
100-----------80
50------------40

5.Divide 50 by 2 = 25%:

%--------------#
100------------80
50-------------40
25-------------20

Now we know that 25% of 80 is 20. Another way we would've done it is 100 divided by 4:

%<------------->#
100-----------80
25------------20

And here is a video of another way of finding the Percent of a Number:
