Answer:
Each brother of maria will receive 7/30 of the whole pizza
Step-by-step explanation:
First we have to calculate the amount of pizza that Maria gave to her brothers
For this we have to subtract the 3/10 that was eaten from 1
1 can also be written as 10/10
1 = 10/10
10/10 - 3/10 = 7/10
Maria gave her brothers 7/10 of the pizza
If your brothers were 3 and received the same amount, to know how much each one received we have to divide 7/10 by 3
(7/10) /3 = 7/30
Each brother of maria will receive 7/30 of the whole pizza
