Henry had
16 as many erasers as Fabian. Fabian had twice as many erasers as Charlie. If Henry had 74 erasers fewer than Charlie,
- how many erasers did Henry have?
- how many erasers did they have altogether?
(a)
Number of erasers that Henry had = 1 u
Number of erasers that Fabian had = 6 u
Number of erasers that Charlie had = 6 u ÷ 2 = 3 u
Number of erasers that Henry had fewer than Charlie
= 3 u - 1 u
= 2 u
2 u = 74
1 u = 74 ÷ 2 = 37
Number of erasers that Henry had
= 1 u
= 37
(b)
Total number of erasers that they had
= 1 u + 6 u + 3 u
= 10 u
= 10 x 37
= 370
Answer(s): (a) 37; (b) 370
