O<br> Decrease 40 by ratio of 4:5
Reika [66]

A decrease in the ratio 4:5 implies that :

New quantity:Old quantity = 4:5

Let the new quantity be \bf \: x

\bf∴ x : 40 = 4:5

=  > \bf \frac{x}{40}  =  \frac{4}{5}

\bf =  > 40 \times  \frac{x}{40}  = 40 \times  \frac{4}{5}

\bf =  > x = 8 \times 4

\bf =  > x = 32

So, the new quantity is 32
