Question

if a:b =5:7 and b: c =14 :15 , find a: c​

Answer 1

Answer:

given a: b = 5 : 7

a / b = 5 / 7 -----(1)

b : c = 14:15

b / c = 14 / 15----(2)

multiply equation (1) and eq.(2)

a / b × b / c = 5 / 7 × 14 / 15

a / c = 5× 2 /15

a /c = 2 / 3

hence a : c =2 :3

Step-by-step explanation:

Hope it helped u my dear frnd!!

Answer 2

a:c=2:3

Step-by-step explanation:

given a:b = 5:7

a/b = 5/7 ------( 1 )

b:c = 14:15

b/c = 14/15 -----( 2 )

multiply eq. ( 1 ) and ( 2 )

a/b ×b/c = 5/7 × 14/15

a/c = 5 × 2/15

a/c = 2/3

hence a:c = 2:3
