I want to know how to multiply a fraction.

Multiply the top numbers (the numerators)

2nd multiply the bottom number is (the denominator) and 3rd simplify the fraction if needed

Multiply the numerators then divide the denominators

for example

1/2 x 3/4

(1 x 3=3)

(2 x 4=8)

answer=3/4

in division, write the first equation, change the sign and then reciprocate the second equation.

for example

1/2 divided by 3/4

1/2 x 4/3

answer=2/3
