To solve (7/10) / (4/5), we must remember how to divide fractions - it is the same as multiplying the fractions except we take the reciprocal of the second fraction. This is modeled below:
7/10 * 5/4
Next, we multiply both the numerators and the denominators together, creating one, larger, fraction.
(7 * 5) / ( 10 * 4) = 35/40
To simplify this fraction, we have to divide both the numerator and the denominator by the GCF, or greatest common factor, of 5.
(35/5) / (40/5) = 7/8
Therefore, your answer is 7/8.
Hope this helps!
