Question

If a:b =5:7 and b:c =6:11 then a:b:c equal to wat

Answer 1

Answer:

30/77

Step-by-step explanation:

a/b=5/7=(5*6)/(7*6)=30/42

b/c=6/11=(6*7)/(11*7)=42/77

therefore

a/c=30/77

Answer 2

Answer:

30:42:77

Step-by-step explanation:

a:b =5:7

a/b =5/7

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

b:c =6:11

b/c =6/11

c=11b/6 ....(2)

Taking b=7×6=42

Substituting the value of b in (1) and (2)

$a = \frac{5b}{7} = \frac{5 \times 42}{7} = 30 \\ c = \frac{11b}{6} = \frac{11 \times 42}{6} = 77$

a:b:c=30:42:77
