## Faman39 2 years ago Which of the following would you use as the percent equation to determine that 70 is 40% of what number? 40 = 0.7 * a a = 0.7 * 40 a = 0.4 *70 70 = 0.4 *a

1. y2o2

a = 0.4 *70

2. y2o2

$a = {{40\over 100} \times 70} = 0.4 \times 70$

3. Faman39

a = 0.7 * 40

4. Faman39

Right?

5. Chlorophyll

Look at the way I translate " 70 is 40% of what number? " 70 = .4 * a

6. Faman39

70 = 0.4 *a
