What is 3/4 of 16/21? worked out please

timofeeve [1]

Of means multiplication

So

$\frac{3}{4} \sf{of} \frac{16}{21} = \frac{3}{4} \times \frac{16}{21}$

And then simplify the numerator ad denominator

= $\frac{3 \times 16}{4 \times 21} = \frac{\ 1 \times 16}{4 \times 7}$

And simplify the numerator and denominator again

= $\frac{\ 1 \times 16}{4 \times 7} = \frac{\ 1 \times 4}{1 \times 7}$

And we are finally left with the answer which is $\frac{4}{7}$
