Number of marbles that Liam had before = 11 u
Number of marbles that Liam gave to Albert = 2 u
Number of marbles that Liam gave to Perry = 2 u
Number of marbles that Liam gave to Harry = 1 u
Number of marbles that Liam had left = 6 u
6 u = 12
1 u = 12 ÷ 6 = 2
Number of marbles that Liam had at first
= 11 u
= 11 u x 2
= 22
