Question

ratio in the simplest form : if A:B = 7:5 and B:C= 10:13 find A : B : C​

Answer 1

Answer:

A:B = 3:5 (1)

B:C = 10:13. (2)

So LCM of both values of B = 5 and 10 = 10

So multiply (1) by 2

So A:B:C

= 6:10:13 , which is in the simplest ratio

Answer 2

$\huge \fcolorbox{black}{cyan}{♛answer♛} \\ A:B = 7:5 \\ = > \frac{A}{B} = \frac{7}{5} = \frac{7 \times 2}{5 \times 2} = \frac{14}{10} \\ B:C= 10:13 \\ = > \frac{B}{C} = \frac{10}{13} \\ so \: A : B : C = 14 : 10 : 13$
