Kenny’s weight is 6/7 times Melvin’s weight.
Mazyrski [523]

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
