Ivan had
110 as many beads as Asher. Asher had twice as many beads as Daniel. If Ivan had 112 beads fewer than Daniel,
- how many beads did Ivan have?
- how many beads did they have altogether?
(a)
Number of beads that Ivan had = 1 u
Number of beads that Asher had = 10 u
Number of beads that Daniel had = 10 u ÷ 2 = 5 u
Number of beads that Ivan had fewer than Daniel
= 5 u - 1 u
= 4 u
4 u = 112
1 u = 112 ÷ 4 = 28
Number of beads that Ivan had
= 1 u
= 28
(b)
Total number of beads that they had
= 1 u + 10 u + 5 u
= 16 u
= 16 x 28
= 448
Answer(s): (a) 28; (b) 448
