Let the number of nickels be x, the number of dimes is x+8
but
1 nickel=$0.05 
1 dime=$0.1
thus, the total amount Susan has will be:
0.05x+0.1(x+8)=3.05
0.05x+0.1x+0.8=3.05
0.15x=2.25
x=2.25/0.15
x=15
thus the number of nickels is 15
number of dimes is 15+8=23

Answer/Step-by-step explanation:

Quotient is simply the ratio of the first numerator to the second numerator:

Let's \frac{x_1}{y}\;and\;\frac{x_2}{y} are two fractions in same terms.

Thus, \frac{x_1}{y}\div\frac{x_2}{y} {Divided by a fraction is equal to multiplied by its reciprocal}

=\frac{x_1}{y}\times\frac{y}{x_2}

Quotient is simply the quotient of their numerators.

Example could be:

\frac{2}{7}\div\frac{3}{7}

\frac{2}{7}\times\frac{7}3}

\frac{2}{3}

2 is first numerator and 3 is the second numerator.

11/15% of a quantity is equal to what fraction of the​ quantity?
Contact [7]

Percent means “out of 100.” So 5% really means 5/100.

11 / 15% = 11 / (15/100) = 1100 / 15 = 220 / 3. That’s the answer.
