Question

Tom had 5 times as many marbles as weiming. After Tom gave 64 marbles to weiming , both boys had the same number of marbles. How many marbles did Tom have at first?​

Answer 1

Answer:

160

Step-by-step explanation:

5:1

5-64=1+64

5=1+128

5x-1x=128

4x=128

x=32

32*5=160

Answer 2

let the weiming's marble be x

=> Tom's marble is 5x

after giving 64 marbles

weiming's marble = x+64

Tom's marble = 5x-64

as per given conditions

5x-64=x+64

=> 4x=128

=>x=32

so, at beginning tom have 5×32=160marbles
