Answer 2

Yes, 56, 64, 63, 72 numbers are in proportional.

Step-by-step explanation:

To find : Are the following number proportional 56, 64, 63, 72 ?

Solution :

We know that,

The numbers are in proportional $a:b::c:d$ then, $\frac{a}{b}=\frac{c}{d}$ i.e. product of extremes  = product of middle terms.

Here, a=56,b=64, c=63 and d=72

Substitute,

$\frac{56}{64}=\frac{63}{72}$

$\frac{8\times 7}{8\times 8}=\frac{9\times 7}{9\times 8}$

$\frac{7}{8}=\frac{7}{8}$

They are equal so 56, 64, 63, 72 numbers are in proportional.
