Answer:
a.24kg
Step-by-step explanation:
4:6=120
4+6=120
10=120
10/10=120/10
0=12
so, 12(4) + 12(6) =120
48+72=120
120=120, which is true.
therefore, sam = 48kg and gregory =72kg
it is asked in the problem that how much heavier is Gregory than Sam, that makes us to subtract the weight og the two,
72kg - 48kg = 24kg
