Asupplier sells 2 1/4 pounds of mulch for every 1 1/3 pounds of gravel. the supplier sells 172 pounds of mulch and gravel combined. how many pounds of each item did the supplier sell?

We first write the fractions in their decimal forms and find out the ratio.

2 1/4 is equivalent to 2.25, and 1 1/3  is equivalent to 1.33

Ratio will be 2.25 / 1.33 = 1.69  or 1.7 rounded off. Since it cannot be simplified further, then the ratio of mulch to gravel will be 1.7: 1

Quantity of mulch sold → 1.7/2.7 of 172 →0.629 ×172 = 108.2 pounds

Quantity of gravel sold will be  172 -108. 2 = 63 .8 pounds
