Question

F Harry can complete ⅖ of a math problem in ⅙ of a minute, how many problems can he complete per minute?

A) 1.2 problems per minute
B) 0.5 problems per minute
C) 0.8 problems per minute
D) 2.5 problems per minute

Answer 1

Harry can complete 2.4 problems per minute.

Step-by-step explanation:

To find out how many problems Harry can complete per minute, we can use a proportion. We know that Harry can complete 2/5 of a problem in 1/6 of a minute. Let's set up the proportion:

2/5 problems / 1/6 minute = x problems / 1 minute

To solve for x, we can cross-multiply and divide:

2/5 * 1 = x * 1/6

x = 2/5 * 6

x = 12/5

x = 2.4 problems per minute

Therefore, Harry can complete 2.4 problems per minute.
