1. FRACTION BASICS

2. Fraction to Decimal
𝐷𝑖𝑣𝑖𝑑𝑒 𝑡ℎ𝑒 Nume𝑟𝑎𝑡𝑜𝑟 𝐷𝑒𝑛𝑜𝑚𝑖𝑛𝑎𝑡𝑜𝑟 =𝐷𝑒𝑐𝑖𝑚𝑎𝑙 1 4 = = = =1 These are the benchmark fractions/decimals

3. Decimal to Percent… Percent to Decimal
1 4 = = = =1 Just need to multiply by 100% once in decimal form 0.25 x 100% = 25% Just need to divide by 100% once in percent form 25% ÷ 100% = 0.25

4. To write any decimal as a fraction, just use place value
0.6
there is a 6 in the tenths place
6/10
b) 0.53
there is a 53 in the hundredths place
53/100 
c) 0.774
there is a 774 in the thousandths place
774/1000

5. Quarter to three, Quarter after three
2:45 & 3:15
Quarter is 25 cents
25 cents is actually 25 out of 100, which is a dollar
= ….. Equivalent fractions
Quarter of sixty minutes is 15 minutes……

6. Equivalent Fractions
You can find any equivalent fraction by multiplying or dividing the numerator and denominator by the exact same number.
x 4 =
x 4

7. Reduce the fraction into “simplest form” \ i.e. “lowest terms”
÷ 5
Find the biggest number that both the numerator and denominator are divisible by. =
÷ 5

8. Improper Fraction / Mixed Number
9 4
See how many times the denominator goes into the numerator
(that is your whole number) and whatever is left over is your new fraction.
2 1 4
9 ÷ 4 = 2, leaves 1 as remainder
Multiply the denominator by the whole number and then add the numerator. That answer becomes your new numerator and the denominator stays the same.
2 3 4 11
4 x 2+ 3 =
11 4

9. Adding Fractions + 7, 14, 21, 28, 35 We need a common
Count by 2's +
2, 4, 6, 8, 10, 12, 14, 16, 18, 20
Count by 7's
7, 14, 21, 28, 35
We need a common
denominator to add
these fractions.
The first number IN COMMON
that appears on both lists
becomes the common denominator

11. Subtracting Fractions
4 5 − 4 10
common denominator is 10
Do not need to change as 10 is already in the denominator -
x 2
8−4 10
4 10
4 5 10 8 =
x 2
