In a box, 50% of the beads are silver, 20% are grey and the rest are gold
- What fraction of the beads is gold? Give your answer in the simplest form.
- There are 417 gold beads in the box. How many beads are there in the box altogether?
(a)
Percentage of beads that are gold
= 100% - 50% - 20%
= 30%
Fraction of beads that are gold
=
30100 =
310 (b)
Number of gold beads = 3 u
3 u = 417
1 u = 417 ÷ 3 = 139
Total number of beads
= 10 u
= 10 x 139
= 1390
Answer(s): (a)
310; (b) 1390
