To evaluate \( \frac{5}{2} \div \frac{7}{4} \), you can multiply by the reciprocal of the second fraction:
\[
\frac{5}{2} \div \frac{7}{4} = \frac{5}{2} \times \frac{4}{7}
\]
Now, multiply the numerators and the denominators:
\[
= \frac{5 \times 4}{2 \times 7} = \frac{20}{14}
\]
Next, simplify the fraction \( \frac{20}{14} \) by finding the greatest common divisor (GCD) of 20 and 14, which is 2:
\[
\frac{20 \div 2}{14 \div 2} = \frac{10}{7}
\]
Thus, the simplified answer is \( \frac{10}{7} \) or 10 sevenths.
The correct response is:
**10/7**
**10 sevenths**
\[
\frac{5}{2} \div \frac{7}{4} = \frac{5}{2} \times \frac{4}{7}
\]
Now, multiply the numerators and the denominators:
\[
= \frac{5 \times 4}{2 \times 7} = \frac{20}{14}
\]
Next, simplify the fraction \( \frac{20}{14} \) by finding the greatest common divisor (GCD) of 20 and 14, which is 2:
\[
\frac{20 \div 2}{14 \div 2} = \frac{10}{7}
\]
Thus, the simplified answer is \( \frac{10}{7} \) or 10 sevenths.
The correct response is:
**10/7**
**10 sevenths**
