Answer:
Step-by-step explanation:
We first have to write an expression for each of the types of coins in terms of one of them. If he has 8 more dimes than nickels, let's call nickels "x". That means that dimes is "x + 8". The value of a nickel is .05, so the expression relating the number of nickels to the worth of the nickel is .05x. The value of a dime is .10, so the expression relating the number of dimes to the worth of the dime is .10(x + 8). The total value of these coins is 1.70:
.05x + .10(x + 8) = 1.70 and
.05x + .10x + .8 = 1.70 and
.15x = .9 so
x = 6
That means we have 6 nickels and 14 dimes.

Answer:
4/45
Step-by-step explanation:
when dividing fractions, you multiply the first fraction by the second fraction's reciprocal :
1/9 divided by 5/4
1/9 multiplied by 4/5
essentially, you switch the signs from division to multiplication, and reverse the second fraction.
1/9 multiplied by 4/5
1/9*4/5 = 4/45
