Fine 30% of 70. The word of means multiply.
0.30 x 70 = 21
3. What percent of 56 is 14.
We don't know percent so we call it y. Remembering that of means multiply, we have y*56=14
solve for y. I get y = 14/56 = 0.25 as a decimal. You convert decimals to percents by multiplying by 100 (which is the same as moving the decimal to the right 2 places so 0.25 = 25%)
I think these two methods will solve most of the problems.
Check my work. I'm bad about typos.

hat percent of 130 liters is 1.95 liters? find the percent using the percent equation
Sure! I'll help you with each of these questions step-by-step.
1. To find 30% of 70, you can multiply 70 by 0.3 (which is the decimal form of 30%). Therefore, 30% of 70 is calculated as follows:
30% * 70 = 0.3 * 70 = 21
2. To calculate 80% of 65, you can multiply 65 by 0.8 (which is the decimal form of 80%). So, 80% of 65 is:
80% * 65 = 0.8 * 65 = 52
3. To determine what percent of 56 is 14, you need to divide 14 by 56 and then multiply by 100 to convert it to a percentage. The calculation is as follows:
(14 / 56) * 100 = 0.25 * 100 = 25%
4. To find what percent 36 is of 40, divide 36 by 40 and multiply by 100. It can be calculated as follows:
(36 / 40) * 100 = 0.9 * 100 = 90%
5. To determine what number 80 is 40% of, you need to divide 80 by 40% (0.4). The calculation is as follows:
80 / 0.4 = 200
6. To find what number 65% of is 78, you need to divide 78 by 65% (0.65). The calculation is as follows:
78 / 0.65 ≈ 120
7. To calculate what percent of 2000 is 6, divide 6 by 2000 and multiply by 100. It can be calculated as follows:
(6 / 2000) * 100 = 0.003 * 100 = 0.3%
8. To determine what percent 12 is of 4000, divide 12 by 4000 and multiply by 100. It can be calculated as follows:
(12 / 4000) * 100 = 0.003 * 100 = 0.3%
9. To find what percent of 3000 is 18, divide 18 by 3000 and multiply by 100. The calculation is as follows:
(18 / 3000) * 100 = 0.006 * 100 = 0.6%
10. To calculate 110% of 80, you can multiply 80 by 1.10 (which is the decimal form of 110%). Therefore, 110% of 80 is calculated as follows:
110% * 80 = 1.10 * 80 = 88
11. To find 180% of 160, multiply 160 by 1.80 (which is the decimal form of 180%). Therefore, 180% of 160 is calculated as follows:
180% * 160 = 1.80 * 160 = 288
12. To determine 4% of what number is 11, divide 11 by 4% (0.04). The calculation is as follows:
11 / 0.04 = 275
I hope this helps! Let me know if you have any further questions.
