Question

Kenny's weight is 6/7 times melvin's weight. what is the ratio of melvin's weight to the total weight of the two boys?

Answer 1

Answer=7:13

Kenny's Weight*6/7=Melvin's Weight

So, for example, if Melvin's weigh was 7...

Kenny's Weight*6/7=7
divide both sides by 6/7
Kenny Weight=6

So we can say that Melvin's weight to Kenny's weight is 7:6

The boys total weights would be...
7+6=13


So Melvin's weight over the total weight of the two boys is:

7:13

Answer 2

`(7)/(13)`

Explanation:

Let

x------> Melvin's weight

y------> Kenny's weight

we know that

`y=(6)/(7)x`

`x+y=x+(6)/(7)x=(13)/(7)x` -----> total weight of the two boys

Find the ratio of Melvin's weight to the total weight of the two boys

`ratio=(x)/(((13)/(7)x)) =(7)/(13)`
