m varies n ....

Where ..

n1 = 15

m1 = 25

n2 = 87

and let m2 = x ....


A/Q ..


$\frac{n1}{m1} = \frac{n2}{m2} \\ \\ \frac{15}{25} = \frac{87}{x} \\ \\ \frac{3}{5} = \frac{87}{x} \\ \\ 3x = 87 \times 5 \\ \\ 3x = 435 \\ \\ x = \frac{435}{3} \\ \\ x = 145 \\ \\ so \: m2 = 145$



The value of m when n = 87 is 145 ...
