Question

A supplier sells 2 and 1/4 pounds of mulch for every 1 and 1/3 pounds of gravel. The supplier sells 172 pounds of mulch and gravel combined. How many pounds of each item does the supplier sell?  can you please answer with ratios?

Answer 1

Because ratios can be written as fractions

`(mulch)/(2.25)=(gravel)/(1.33)`

172 =
`(mulch)/(2.25)+ (gravel)/(1.33)`
172 -
`(mulch)/(2.25)` =
`(gravel)/(1.33)`
76.44 mulch = x amount of gravel = 172
Gravel = 172 - 76.44
= 95.56
