<h3>
Answer: 32</h3>
==================================================
Explanation:
- b = number of boys = 12
- g = number of girls = unknown
The ratio of boys to girls is 3 to 5, which means,
b/g = 3/5
12/g = 3/5 ... plug in b = 12
12*5 = g*3 ... cross multiply
60 = 3g
3g = 60
g = 60/3 .... divide both sides by 3
g = 20 is the number of girls
b+g = 12+20 = 32 total students in the chess club.
Answer:
The original number is 5.
Step-by-step explanation:
If one number is x then the other is 3x.
Adding 5 to both numbers we get x + 5 and 3x + 5 and we are also given that (3x + 5) = 2(x + 5)
3x + 5 = 2x + 10
3x - 2x = 10 - 5
x = 5.
