Question

Emily baked a cake in 42.5 minutes. She finished making dinner 9 1/10 minutes sooner than the cake. How long did it take her to make dinner? Hint: Change the 9 1/10 to a decimal.

Answer 1

To change 9 1/10 to a decimal, we can add 9 to 1/10:

9 + 1/10 = 9 + 0.1 = 9.1

So, Emily finished making dinner in 9.1 minutes.

Since Emily finished making dinner 9.1 minutes sooner than the cake, we can subtract 9.1 from 42.5:

42.5 - 9.1 = 33.4

Therefore, it took Emily 33.4 minutes to make dinner.
