Question

if A: B = 3 : 5 and B : C = 10 : 13 find A: B : Cin maths ratio and propriton

Answer 1

$A:B = 3:5 = 3 \times 10:5 \times 10 = 30:50 \\ \\ B:C = 10:13 = 10 \times 5:13 \times 5 = 50:65 \\ \\ \therefore A:B:C = 30:50:65 = \bold{6:10:13}$

Answer 2

here's your answer

A:B=3:5 AND,
B:C=10:13

A/B=3/5
B/C=10/13

SO A:B:C=?

A/B=3×2=6/5×2=10
B/C=10×1=10/13×1=13

A:B:C=6:10:13
