Tom had some beads. He gave
23 of his beads to Elijah and bought 4 new beads. After that, he gave
58 of his remaining beads to his brother and bought another 7 new beads. In the end, Tom had 25 beads.
- How many beads did Tom give to his brother?
- How many beads did Tom have at first?
(a)
Fraction of his remaining beads after he gave to his brother
= 1 -
58=
38 38 of his remaining beads = 25 - 7 = 18
18 of his remaining beads = 18 ÷ 3 = 6
58 of his remaining beads = 5 x 6 = 30
Number of beads that Tom gave to his brother = 30
(b)
88 of his remaining beads = 8 x 6 = 48
Fraction of his total beads after he gave to Elijah
= 1 -
23=
13 13 of his total beads = 48 - 4 = 44
33 of his total beads = 3 x 44 = 132
Number of beads that Tom had at first = 132
Answer(s): (a) 30; (b) 132
