Step-by-step explanation:

To calculate 27% of 84 using 1%, 5% and 10%, you can break down 27% into 10% + 10% + 5% + 1% + 1%. First, we'll find these percentages of 84 and then add them up to get the final answer. To calculate 27% of 84, you find 10%, 5%, and 1% of 84 and add them up.

The calculation involves simple arithmetic: 10% of 84 is 8.4, 5% is 4.2, and 1% is 0.84. The sum of these percentages gives you 27% of 84, which is 22.68.

1. Calculate 10% of 84 by moving the decimal point one place to the left: 84 * 10% = 84 * 0.10 = 8.4.
2. Now, calculate 5% of 84 by halving the value of 10%: 5% of 84 = 8.4 / 2 = 4.2.
3. To find 1% of 84, move the decimal point two places to the left: 84 * 1% = 84 * 0.01 = 0.84.
4. Now, add up the values: 8.4 (10%) + 8.4 (another 10%) + 4.2 (5%) + 0.84 (1%) + 0.84 (another 1%) = 22.68.

The calculation shows that 27% of 84 is 22.68.
