Can someone ? asap! (17 pts and brainliest) a supplier sells 2 1/4 pounds of mulch for every 1 1/3 pounds of gravel. if the supplier sells 172 pounds of both mulch and gravel combined, how many pounds of mulch did he sell? (explain)

I did this problem last year, if I remember you do this:

64 pounds of gravel and 108 pounds of mulch will be the outcome

*2 1/4 will be equal to 2.25
*1 1/3 will be equal to 1.33

2.25 / 1.33 = 1.7 is fine (rounded up)

*ratio of gravel = 1.7: 1

FOR MULCH:
1.7/2.7 from 172 you will use the outcome 0.629 * 172 to get 108.2 pounds

FOR GRAVEL:
172 - 108.2 = 63.8 pounds

Totals sold will be: 
- 108 Pounds 
- 64 Pounds 

25 is obviously the correct answer
