- There are 560 gold erasers in the box. How many erasers are there in the box altogether?
(a)
Percentage of erasers that are gold
= 100% - 50% - 18%
= 32%
Fraction of erasers that are gold
=
32100 =
825 (b)
Number of gold erasers = 8 u
8 u = 560
1 u = 560 ÷ 8 = 70
Total number of erasers
= 25 u
= 25 x 70
= 1750
Answer(s): (a)
825; (b) 1750
