Step-by-step explanation:
Vina has $4.70 in quarters, dimes and nickels in her purse. She has nine more dimes than quarters and four more nickels than quarters. How many of each coin are in her purse?
nickels
dimes
quarters
p = (1/r) - q
In order to find this, follow the order of operations to get the answer.
1/p+q = r ----> Multiply both sides by p+q
1 = r(p + q) -----> Divide by r
1/r = p + q -----> subtract q from both sides
(1/r) - q = p
1/10 = .1, and 3/33 = .0909090... it is equivalent if you estimate.
Answer:
2 7/20
Step-by-step explanation:
So Lets put these into a fraction form
Petra: 5 3/5
Pauline: 3 4/16 -> Can be Simplified = 3 1/4
Take the number of pies Petra Ate and subtract it by the number of pies Pauline ate
Change the numbers to a common factor. (multiply 3/5 by 4 and 1/4 by 5 to have common denominators)

Make These Into a Mixed Fraction

Subtract 112-65

Simplify (divide 47 into 20 how many times to get into a mixed fraction)

I think this is right. Hope This Helps
