Question

Randa used 4 1/2 gallons of water each time she washes dishes if she washes five time will she use gallons of water if she uses more than 20 gallons how much more will she use

Answer 1

If she washes the dishes 5 times she uses 22.5 gallons. If she uses more than 20, she uses 2.5 extra. We get this by multiplying 4 1/2 by 5

4*5=20

1/2*5= 5/2=2.5

20+2.5=22.5
