Mr. Greg had 8 sandwiches. He gave 1/4 to Nehamiah, 1/4 to Elijah, and 1/4 to Elizabeth. How many sandwiches did Mr. Greg have l

SVEN [57.7K]

There are many ways to work this out. One way could be:

Add up:
1/4 + 1/4 + 1/4 = 3/4

Find 3/4 of 8 so;
8 / 4 = 2
2 x 3 = 6

Find what's remaining:
8 - 6 = 2

So Mr.Greg has sandwiches left.
Hope it helped :)

cross multiply:

21*9 = 189

7*q = 7q

so you have 189/7q

divide 189 by 7 to get q

189 / 7 =27

q = 27
