Ответ:
If her spelling quiz was 9 minutes and her math quiz was 3 times as long you find that answer by doing the following math.
9x3=27 minutes (time for her math quiz)
27 minutes + 9 minutes = 36 minutes
40 minutes - 36 minutes = 4 minutes
Ответ:
9×3
=27
We cam then find how many time she leftover:
40-9-27
=4mins
Therefore 4 minutes were leftover.
Hope it helps!
