Multiplication Fractions = Think $1/2$

Whenever you see the word fractions think of $1/2$

$It is easiest to start with a half to multiply fractions$

The fractured (fraction) rock was split in half ( $1/2$ )

To remember how to calculate fractions always think of a $1/2$ and work it out from there:

Start with a half its easiest

From this, you can use logic and ask yourself how do you get from $1/2$ of a $1/2$ to equal a $1/4$

It must be: $(1times1)/(2times2)=1/4$ (It couldn’t be anything else)

So use this logic for all other multiplication of fractions.

Example 1

Work out $3/4\ times1/3$

Multiply the top numbers then the bottom numbers together

Therefore $3/4\ times1/3=(3\times1)/(4times3)=3/12\ or\ 1/4$

Example 2

What is $1/2\times 1/3$

Multiply the top numbers then the bottom numbers together

Therefore $1/2\ times1/3=(1times1)/(2times3)=1/6$

Example 3

Work out $1\3/4\times2\1/2$

This means work out $7/4\times5/2$

Multiply the top numbers then the bottom numbers together

Therefore $7/4\times5/2=35/8\ or\ 4\3/8$

NOTE:

Do this on any multiplication of a fraction and you will always get the correct answer.
