Question

multiplying fractions. multiply. $\frac{2}{5}\times\frac{7}{9}=square$

Explanation:

Step1: Recall fraction - multiplication rule

To multiply two fractions $\frac{a}{b}$ and $\frac{c}{d}$, the formula is $\frac{a}{b}\times\frac{c}{d}=\frac{a\times c}{b\times d}$. Here, $a = 2$, $b = 5$, $c = 7$, and $d = 9$.

Step2: Calculate the product of numerators and denominators

The product of the numerators is $2\times7 = 14$, and the product of the denominators is $5\times9=45$. So, $\frac{2}{5}\times\frac{7}{9}=\frac{2\times7}{5\times9}=\frac{14}{45}$.

Answer:

$\frac{14}{45}$
