Question

multiply.
try using the cross-cancel strategy to simplify the problem
answer as a fraction in simplest form.
$\frac{4}{9} \times \frac{9}{10} = \frac{?}{}$
enter the numerator

Explanation:

Step1: Cross-cancel common factors

The numerator 9 and denominator 9 are equal, so they cancel out:
$\frac{4}{\cancel{9}} \times \frac{\cancel{9}}{10} = \frac{4}{1} \times \frac{1}{10}$

Step2: Multiply numerators and denominators

Multiply the remaining numerators and denominators:
$\frac{4 \times 1}{1 \times 10} = \frac{4}{10}$

Step3: Simplify the fraction

Divide numerator and denominator by their greatest common factor (2):
$\frac{4 \div 2}{10 \div 2} = \frac{2}{5}$
