Question

A dwarf seahorse swims 3/4 inch in a minute. How many minutes would take the seahorse to swim 1/3 inch?

A. 1/3 divided by 3/4= 4/9
B. 1/3 times 3/4= 1/4
C. 3/4 divided by 1/3= 9/4
D. 3/4 + 1/3= 13/12

Answer 1

A

Explanation:

we have 3/4 in / minute.

so, we divide this by 3/4 to get the time for 1 inch.

and then we multiply by 1/3 to get the time for 1/3 inch.

that combination, dividing by 3/4 and multiplying by 1/3, can be done in any sequence (commutative property of multiplication).

therefore, this can be expressed as 1/3 divided by 3/4. and A is the correct answer.
