irina [24]

Answer:

2\frac{5}{8}\ gal

Step-by-step explanation:

step 1

Convert mixed number to an improper fraction

so

5\frac{1}{4}\ gal=\frac{5*4+1}{4}=\frac{21}{4}\ gal

step 2

Divide the total gallons of paint by two

\frac{(21/4)}{2}=\frac{21}{8}\ gal

step 3

Convert improper fraction to mixed number

\frac{21}{8}\ gal=\frac{16}{8}+\frac{5}{8}=2+\frac{5}{8}=2\frac{5}{8}\ gal

malfutka [58]
Amy=n
Chris=n+18

Amy=n=36pounds
Chris=n+18=54pounds
