Answer 1

Answer:

let the ratios be 4xand 7x

so 4x+7x=132

11x=132

x=132÷11

x=12

4x=12×4

=48

and

7x=12×7

=84

hope this helps

Answer 2

The answer is 4.8, 8.4

 Let the ratio = 4x, 7x

⇒ 4x + 7x  = 13.2

⇒          11x = 13.2

⇒             x = $\frac{13.2}{11}$

⇒                 =  $\frac{132}{11 * 10}$

⇒                 = $\frac{12}{10}$

Thus, 4x = $4 * \frac{12}{10}$

               = $\frac{48}{10}$

               = 4.8

Also, 7x = $7 * \frac{12}{10}$

              = $\frac{84}{10}$

             = 8.4

Thus the answer is = 4.8, 8.4
