Answer

$\frac{8}{5}$

Work Step by Step

We can write the given ratio as a fraction and then simplify in lowest terms. Since 1 dollar has 4 quarters, we can write 4 dollars as $(4\times4)=16$ quarters. $\frac{16quarters}{10quarters}$ Since both the denominator and numerator have the same unit, we can divide out the common unit. $\frac{16}{10}=\frac{16\div2}{10\div2}=\frac{8}{5}$
