$\red{ \frac{1}{2} \times 7.5 \times 7.5}$

$Convert \: decimal \: number7.5 \: to \: fraction \frac{75}{10} \\ . Reduce the \: fraction \: \frac{75}{10} \\ \: to \: lowest \: terms \: by \: extracting \: and \: canceling \: out$

$\red{ \frac{1}{2} \times ( \frac{15}{2} ) \times 7.5}$

Multiply 1/2 times 15/2 by multiplying numerator times numerator and denominator times denominator.

$\red{ \frac{1 \times 15}{2 \times 2} \times 7.5}$

Do the multiplications in the fraction 1×15/2×2.

$\red {\frac{15}{4} \times 7.5}$

Convert decimal number 7.5 to fraction 75/10. Reduce the fraction 75/10 to lowest terms by extracting and canceling out 5.

$\red{ \frac{15}{4} \times ( \frac{15}{2} )}$
