Number of erasers that Gabriel had before = 11 u
Number of erasers that Gabriel gave to Luke = 2 u
Number of erasers that Gabriel gave to Fred = 1 u
Number of erasers that Gabriel gave to Daniel = 3 u
Number of erasers that Gabriel had left = 5 u
5 u = 15
1 u = 15 ÷ 5 = 3
Number of erasers that Gabriel had at first
= 11 u
= 11 u x 3
= 33
