Answer:
(a) 2/3
(b) 45
Explanation:
(a)
The "ratio of shirts to skirts" means "the number of shirts divided by number of skirts."
10 shirts
15 skirts
shirts : skirts = 10/15 = 2/3
Answer: 2/3
(b)
In the simplified ratio, there are 2 shirts for every 3 skirts.
Add 2 + 3 = 5.
The ratio of skirts to total number of items of clothing is 3:5.
There are 3 skirts to each 5 items of clothing.
Set up a proportion.
3/5 = x/75
5x = 3 * 75
x = 3 * 15
x = 45
Answer: 45
