Question

A student completes 100 multiplication facts in 4 minutes. How long will it take her

to complete 325 facts?

Answer 1

13 minutes

Explanation:

Okay so you take 100 divided by 4 which would be 25

so that means she finishes 25 questions per minute

so, then you take every hundred (there's 3) and you divide that by 4

then you'd get 4 times 3 which would be 12 and then you add an extra minute with the remaining 25

the answer would be 13 minutes!

Answer 2

• 13 minutes

Explanation:

Solve by ratios:

• x / 4 = 325 / 100
• x / 4 = 3.25
• x = 4*3.25
• x = 13
