You don't define the ratio, so there are two answers:
If 2/3 is boys to girls, then,
2/3 = 24/x
x = 36 girls
If 2/3 is girls to boys, then,
2/3 = x/24
x = 16 girls

Let the number of students in the class be x
Let the number of pieces of gum she gave out be 3x
Equation
3x + 8 = 168 This will not work out evenly. Let's try x - 1. The reason for that is because she may not give out anything to herself.
3(x - 1) + 8 = 168 This doesn't work either.
Well we have to choose. It's a rounding problem.
3x + 8 = 168 Subtract 8 from both sides.
3x = 168 - 8 Combine
3x = 160 Divide by 3 on both sides.
x = 160 / 3
x = 53.333333333
Since that can't be, we could say there were 53 students.
3x
3ac(9-3b+5f) you got to do factorization
1. 6×(3+2)÷10 = 3
Work:
3+2 = 5
6 × 5 = 30
30 ÷ 10 = 3
2. 12-(3×3)+11 = 14
Work:
3 × 3 = 9
12 - 9 = 3
3 + 11 = 14
3. (10×0.4) + (10×0.8) = 12
Work:
10 × .4 = 4
10 × .8 = 8
8 + 4 = 12
4.(8 ÷ 4)×(4-2) = 4
Work:
8 ÷ 4 = 2
4 - 2 = 2
2 × 2 = 4
5.8.5-10÷2 = 3.5
Work:
10 ÷ 2 = 5
8.5 - 5 = 3.5
6.18-(8÷2)+25 = 39
Work:
8 ÷ 2 = 4
18 - 4 = 14
14 + 25 = 39
Answer:
807825
Step-by-step explanation:
eight hundred seven thousand is 807000
eight hundred twenty five is 825
807000 + 825 = 807825
