Answer:
20/156 or 5/39
Step-by-step explanation:
the first part of the equation will be:
5/13 (5 is how many blue and 13 is altogether)
the next part of this equation is the green marble. Because we didn't put the blue marble back, the next part of the equation will be:
4/12 (4 is how many green and 12 is altogether now that one blue was taken out)
and from there, you multiply 5/13 with 4/12, with will give you 20/156, or 5/39 if you simplify.

Answer:
Step-by-step explanation:
Given a supplier sells 2 1/4 lbs mulch for every 1 1/3 lbs gravel, you want to know the weight of each if 172 total pounds were sold.
The ratio of pounds sold can be found as ...
mulch : gravel = 2 1/4 : 1 1/3 = 9/4 : 4/3 = 27/12 : 16/12 = 27 : 16
The fraction of mulch sold is 27/(27+16) = 27/43. In pounds, that fraction is ...
(172 lb)(27/43) = 108 lb . . . . . mulch
The rest is sold as gravel:
172 lb -108 lb = 64 lb . . . . . gravel
The supplier sold 108 lb of mulch and 64 lb of gravel.
