Question

if a:b=4:7and b:c=5:7 then a:b:c=? step by step instructions​

Answer 1

Answer:

given that a:b=4:7 & b:c=5:6

given that a:b=4:7 & b:c=5:6We have to calculate a:b:c

given that a:b=4:7 & b:c=5:6We have to calculate a:b:cThus a:b:c

given that a:b=4:7 & b:c=5:6We have to calculate a:b:cThus a:b:c=> (a*b):(b*b):(b*c)

given that a:b=4:7 & b:c=5:6We have to calculate a:b:cThus a:b:c=> (a*b):(b*b):(b*c)=>(4*5):(7*5):(7*6)

given that a:b=4:7 & b:c=5:6We have to calculate a:b:cThus a:b:c=> (a*b):(b*b):(b*c)=>(4*5):(7*5):(7*6)=>20:35:42
