Question

11 4/5 divided by 3 1/5

A) 3
B) 3 1/2
C) 7/2
D) 4

Answer 1

Explanation:

The two given numbers both have the denominator 5, Thus the quotient quickly reduces:

11 4/5 becomes 59/5 and 3 1/5 becomes 16/5. Dividing the first expression by the second yields 59/16, which can't be reduced.

However, 59 = 48 + 11, so 59/16 = 48/16 + 11/16, which is approximately 3 1/2 (from either Answer B or Answer C).

The exact answer is 3 11/16; B and C are identical and are closer to 3 11/16 thn 3 or 4.
