20% of 70 is 14. This can be calculated by multiplying 20/100 with 70, which gives (20/100)70 = (2070)/100 = 14. Alternatively, we can use the following steps to calculate 20% of 70:
- Start with the given output value, which is 14.
- Use the variable x to represent the unknown value.
- From Step 1, we know that 14 is equivalent to 100%.
- Similarly, we can determine that x represents 20% of the value.
- This leads us to two simple equations: 14 / 100% = x / 20%.
- To solve for x, we divide equation 1 by equation 2, considering that both equations have the same unit (%). Thus, we obtain: 70 / x = 100% / 20%.
- By taking the reciprocal of both sides of the equation obtained in Step 6, we have: x / 70 = 20 / 100 ⇒ x = 14.
Therefore, 20% of 70 is 14.
