- There are 560 pink erasers in the box. How many erasers are there in the box altogether?
(a)
Percentage of erasers that are pink
= 100% - 46% - 19%
= 35%
Fraction of erasers that are pink
=
35100 =
720 (b)
Number of pink erasers = 7 u
7 u = 560
1 u = 560 ÷ 7 = 80
Total number of erasers
= 20 u
= 20 x 80
= 1600
Answer(s): (a)
720; (b) 1600
