14=30%×N
85%×N=8.5
50=N×100
150=75%×N
N=115%×100
Answer:
Let's solve each equation step by step:
1. 14 = 30% × N
To find N, we can divide both sides of the equation by 30% (or 0.30):
14 / 0.30 = N
N ≈ 46.67
2. 85% × N = 8.5
To find N, we can divide both sides of the equation by 85% (or 0.85):
8.5 / 0.85 = N
N = 10
3. 50 = N × 100
To find N, we can divide both sides of the equation by 100:
50 / 100 = N
N = 0.5
4. 150 = 75% × N
To find N, we can divide both sides of the equation by 75% (or 0.75):
150 / 0.75 = N
N = 200
5. N = 115% × 100
To find N, we can divide both sides of the equation by 115% (or 1.15):
100 / 1.15 = N
N ≈ 86.96
Therefore, the solutions to the given equations are:
1. N ≈ 46.67
2. N = 10
3. N = 0.5
4. N = 200
5. N ≈ 86.96
