Question

SOMEONE PLEASE HELP

Frank has white and blue bulbs with the ratio of 3:5. It has 45 white bulbs. He wants to change the ratio of white and blue bulb to 1:3. He will keep the same total number of bulbs. How many MORE blue bulbs will there be now?

Answer 1

15 more blue bulbs

Explanation:

3 : 5 = 45 : b

b = 45 · 5 / 3

b = 15 · 5

b = 75

total bulbs = 45 + 75 = 120

1 : 3 = w : b

(1+3) : 3 = (w + b) : b

4 : 3 = 120 : b

b = 120 · 3 / 4

b = 30 · 3

b = 90

90 - 75 = 15
