Question

Theo ate .7 of his candy bar. How many more tenths must he eat to finish the whole candy bar?

Answer 1

Answer:

3 tenths

Step-by-step explanation:

One candy bar

= 1 candy bar

= 1.0, or 10 tenths (one tenth is 0.1)

If Theo eats 0.7 of a candy bar, we know that

1.0 - 0.7 = 0.3

0.3 = 3 *0.1 (one tenth)

Therefore, the answer is 3 tenths.
