In a box, 49% of the cards are green, 17% are red and the rest are yellow
- What fraction of the cards is yellow? Give your answer in the simplest form.
- There are 646 yellow cards in the box. How many cards are there in the box altogether?
(a)
Percentage of cards that are yellow
= 100% - 49% - 17%
= 34%
Fraction of cards that are yellow
=
34100 =
1750 (b)
Number of yellow cards = 17 u
17 u = 646
1 u = 646 ÷ 17 = 38
Total number of cards
= 50 u
= 50 x 38
= 1900
Answer(s): (a)
1750; (b) 1900
