Ahmad had
112 as many erasers as Howard. Howard had four times as many erasers as John. If Ahmad had 94 erasers fewer than John,
- how many erasers did Ahmad have?
- how many erasers did they have altogether?
(a)
Number of erasers that Ahmad had = 1 u
Number of erasers that Howard had = 12 u
Number of erasers that John had = 12 u ÷ 4 = 3 u
Number of erasers that Ahmad had fewer than John
= 3 u - 1 u
= 2 u
2 u = 94
1 u = 94 ÷ 2 = 47
Number of erasers that Ahmad had
= 1 u
= 47
(b)
Total number of erasers that they had
= 1 u + 12 u + 3 u
= 16 u
= 16 x 47
= 752
Answer(s): (a) 47; (b) 752
