Answer:

90 minutes

Explanation:

So 27 = 30%

30% + 30% + 30% = 90%

27 + 27 + 27 = 81

30% ÷ 3 = 10%

27 ÷ 3 = 9

90% + 10% = 100%

81 + 9 = 90

I'm sorry if this is wrong I got kind of confused for a second. But I hope this at least helps.

Answer:

90 Minutes

Explanation:

If he took 27 minutes to do 30% of his homework, then we can reverse the operation to find the total amount

30% is the same as 0.3, therefore you divide 27 by 0.3 because the 100% is 1, so by dividing you'll get the 100%.
