Question

Lauren brings brownies to class one day. She gives 3/5 of them to her friends Gareth, tammy, and Camila. If she gave them 21 brownies, how many did she bring to class?

Answer 1

Answer : 35 brownies
==================================
working:

3/5 = 21
1/5 = 21 / 3
1/5 = 7
5/5 = 7 x 5
1 (the amount of brownies she brought) = 35

Therefore, she brought 35 brownies
