Question

If a: b= 2: 3 and b: c= 4:5, find a:b:c​

Answer 1

Step-by-step explanation

A/B = 2/3

B/C = 4/5

A/B/B/C = 2/3/4/5

A*C/B*B = 2*5/ 3*4

= 10/12

Answer 2

$\huge\blue{\boxed{\underline{a:b:c=8:12:15}}}$

$\tt\underline\pink{Given:}$

a:b=2:3

b:c=4:5

$\tt\underline\pink{To find:}$

a:b:c=?

$\huge\tt\underline\pink{Solution:}$

Since, 3&4 are the factors of 12.So,

a:b=2:3=>2×4:3×4=> 8:12

&

b:c=4:5=>4×3:5×3=>12:15

Hence, the a:b:c=>8:12:15
