Julian had some erasers. He gave
56 of his erasers to Perry and bought 4 new erasers. After that, he gave
49 of his remaining erasers to his cousin and bought another 7 new erasers. In the end, Julian had 27 erasers.
- How many erasers did Julian give to his cousin?
- How many erasers did Julian have at first?
(a)
Fraction of his remaining erasers after he gave to his cousin
= 1 -
49=
59 59 of his remaining erasers = 27 - 7 = 20
19 of his remaining erasers = 20 ÷ 5 = 4
49 of his remaining erasers = 4 x 4 = 16
Number of erasers that Julian gave to his cousin = 16
(b)
99 of his remaining erasers = 9 x 4 = 36
Fraction of his total erasers after he gave to Perry
= 1 -
56=
16 16 of his total erasers = 36 - 4 = 32
66 of his total erasers = 6 x 32 = 192
Number of erasers that Julian had at first = 192
Answer(s): (a) 16; (b) 192
