Peter has 96 stamps and Sam has 63. How many stamps should Sam give Peter so that Peter will have twice as many stamps as Sam?

Sam must give Peter 10 stamps so that Peter has twice as much as him.

Step-by-step explanation:

Although the exercise could be done using equations, I will teach you a much simpler method to find the answer to this type of exercise: add the stamps of Sam and Peter:

96 + 63 = 159

Since one must have twice the other, you will have to divide the total value into 3 (then two parts will correspond to Peter and 1 one to Sam)

159/3 = 53

With this value, Sam must have only 53 stamps and give the rest to Peter, and since Sam has 63 stamps, he will have to give Peter 10, with which Peter will have 106 stamps, which is double 53.

96:2=48

63-48=15

So Sam should give Peter 15 of his stamps so that Peter will have twice as many stamps as him.
