Question

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

Answer 1

of means multiplication

So


`(3)/(4) \sf{of} (16)/(21) = (3)/(4) * (16)/(21)`

And then simplify the numerator ad denominator

=
`(3 * 16)/(4 * 21) = (\ 1 * 16)/(4 * 7)`

And simplify the numerator and denominator again

=
`(\ 1 * 16)/(4 * 7) = (\ 1 * 4)/(1 * 7)`

And we are finally left with the answer which is
`(4)/(7)`
