A. Identify the base, rate, and percentage Then, find the value of the unknown. Given 30% ofhis 1.8 Base Rate Percentar n 1 2 5 790 is n % of 900 3 2.9 is 30% of n a 225 is 25% of n 70% of n is 14.7 6 113 is 13% of 7/28% of n is 196 8 35% of n is 1200 9 14175.5 is 11%6 of n 10 In is 40% of 65
Step-by-step explanation:
1. Base: 1.8, Rate: 30%, Percentage: n%
n% = (30/100) x 1.8
n% = 0.54
Answer: n% = 0.54
2. Base: 790, Rate: n%, Percentage: 900
n% = (900/790) x 100
n% = 113.93
Answer: n% = 113.93
3. Base: n, Rate: 30%, Percentage: 2.9
0.3n = 2.9
n = 9.67
Answer: n = 9.67
4. Base: n, Rate: 25%, Percentage: 225
0.25n = 225
n = 900
Answer: n = 900
5. Base: n, Rate: 70%, Percentage: 14.7
0.7n = 14.7
n = 21
Answer: n = 21
6. Base: 7/28, Rate: 13%, Percentage: 113
(13/100)n = 113 x (7/28)
n = 326
Answer: n = 326
7. Base: n, Rate: 28%, Percentage: 196
0.28n = 196
n = 700
Answer: n = 700
8. Base: n, Rate: 35%, Percentage: 1200
0.35n = 1200
n = 3428.57
Answer: n = 3428.57
9. Base: n, Rate: 11.6%, Percentage: 14175.5
0.116n = 14175.5
n = 122006.03
Answer: n = 122006.03
10. Base: 65, Rate: 40%, Percentage: n
0.4 x 65 = 26
n = 26
Answer: n = 26
