**To change a decimal to percent:**

Multiply it by 100. Add the percent sign. Ex = 23 % 9.1 = 910 % 0.7 = 70 % 45.9 = %

**Answer as fast as you can**

12
**To change a percent to decimal: Divide it by 100. **

Remove the percent sign. Ex. 34% = 0.34 5%= 0.05 1.6% = 0.016 0.6%= 0.006

13
9 % = TRY THESE: 8 % = - % = 2 8 % = 3 10 - 7 7 % =

14
**To change a decimal to fraction, find the fractional equivalence of the place value.**

Ex. 0.7 = 7/10 0.80= 800/100 or 4/5 1.3 = 1 3/10 12.789= /1000

15
Try These: 0.4 0.73 1.2 0.093 30.97

16
**To change a fraction to decimal, divide the numerator by the denominator.**

Ex. ½ = (1÷2) = 0.5 ¾ = 3÷4 = 0.75 7/10 = (7÷10) = 0.7 34/100 = (34 ÷ 100)= 0.34

17
**Answer as fast as you can**

1. 2 9 2. 4 100 3. 3 10 5 20 = 1000
