To find the percentage of a number, you can think of "percent" as "out of 100." A simple way to solve these is to turn the percentage into a decimal and multiply it by the number.
How to do it:
1. Take the percentage number (like 20) and divide it by 100 to get a decimal (0.20).
2. Multiply that decimal by the number you are finding the percentage of.
Let's go through each problem step-by-step:
1.
20% of 60: $0.20 \times 60 = 12$
2.
30% of 90: $0.30 \times 90 = 27$
3.
15% of 60: $0.15 \times 60 = 9$
4.
40% of 30: $0.40 \times 30 = 12$
5.
24% of 50: $0.24 \times 50 = 12$
6.
10% of 100: $0.10 \times 100 = 10$
7.
50% of 50: Half of 50 is 25. ($0.50 \times 50 = 25$)
8.
10% of 60: Move the decimal one place to the left. $60 \rightarrow 6$
9.
77% of 100: Any percent of 100 is just that number. So, 77.
10.
45% of 60: $0.45 \times 60 = 27$
11.
35% of 40: $0.35 \times 40 = 14$
12.
55% of 20: $0.55 \times 20 = 11$
13.
40% of 90: $0.40 \times 90 = 36$
14.
30% of 80: $0.30 \times 80 = 24$
15.
40% of 50: $0.40 \times 50 = 20$
16.
25% of 20: 25% is one-quarter. $20 \div 4 = 5$
17.
20% of 50: $0.20 \times 50 = 10$
18.
80% of 95: $0.80 \times 95 = 76$
19.
55% of 40: $0.55 \times 40 = 22$
20.
12% of 400: $0.12 \times 400 = 48$
Final Answer:
1. 12
2. 27
3. 9
4. 12
5. 12
6. 10
7. 25
