Question

On Monday it rained three-tenths on inch. On Tuesday it rained. Thirty-one hundredths of an inch, and on Wednesday it rained six tenths of an inch. Which day had the greatest amount of rain?

Answer 1

Wednesday

Explanation:

On Monday it rained three-tenths of an inch that is
`(3)/(10)=0.3\ in.`

On Tuesday it rained thirty-one hundredths of an inch that is
`(31)/(100)=0.31\ in.`

On Wednesday it rained six tenths of an inch that is
`(6)/(10)=0.6\ in.`

Now you can compare these decimals. The digit before point is 0 in all three fractions. The first digit after point is 3 in first and second decimal and 6 in third decimal. Since 6 > 3, then 0.6 > 0.3 and 0.6 > 0.31. Thus, the greatest amount of rain was on Wednesday.
