- There are 612 purple erasers in the box. How many erasers are there in the box altogether?
(a)
Percentage of erasers that are purple
= 100% - 47% - 17%
= 36%
Fraction of erasers that are purple
=
36100 =
925 (b)
Number of purple erasers = 9 u
9 u = 612
1 u = 612 ÷ 9 = 68
Total number of erasers
= 25 u
= 25 x 68
= 1700
Answer(s): (a)
925; (b) 1700
