Answer:

$\frac{14}{15}$
$\frac{1}{4}$

Step-by-step explanation:

Given the following equations:

$2\frac{4}{5} \times\frac{1}{3}$
$1\frac{1}{4} \times\frac{1}{5}$

In order to solve the following equations, we convert the mixed numbers into improper fractions and then solve by multiplying the numerators and the denominators by each other.

$2\frac{4}{5} \times\frac{1}{3}$
$2\frac{4}{5} =5\times2=10+4=\frac{14}{5}$
$\frac{14}{5} \times\frac{1}{3}$
$14\times1=14$
$5\times3=15$
$=\frac{14}{15}$

$1\frac{1}{4} \times\frac{1}{5}$
$1\frac{1}{4} =1\times4=4+1=\frac{5}{4}$
$\frac{5}{4} \times\frac{1}{5}$
$5\times1=5$
$4\times5=20$
$\frac{5}{20} \div5=\frac{1}{4}$
$=\frac{1}{4}$

Hope this helps.
