To find what percentage of a number another number is, you can basically just divide it, 21/75 then you can multiply it by 100, so 21/75=0.28, and then 0.28*100=28, 21 is 28 percent of 75
Answer:
Step-by-step explanation:
0.10d + 0.25q = 25.65
q = d + 20
0.10d + 0.25(d + 20) = 25.65
0.10d + 0.25d + 5 = 25.65
0.35d = 25.65 - 5
0.35d = 20.65
d = 20.65 / 0.35
d = 59 <=== there were 59 dimes
q = d + 20
q = 59 + 20
q = 79......there were 79 quarters
