Answer :

To increase 360 by 157%, follow these steps:

1. Understand Percentage Increase:
Increasing a number by a percentage involves calculating the increase amount and then adding it to the original number.

2. Convert the Percentage to a Decimal:
Convert 157% to its decimal form by dividing by 100:
[tex]\[
157\% = \frac{157}{100} = 1.57
\][/tex]

3. Calculate the Increase Amount:
Multiply the original amount (360) by the decimal form of the percentage (1.57):
[tex]\[
\text{Increase Amount} = 360 \times 1.57 = 565.2
\][/tex]

4. Find the Final Amount:
Add the increase amount to the original number to get the final amount:
[tex]\[
\text{Final Amount} = 360 + 565.2 = 925.2
\][/tex]

So, increasing 360 by 157% results in an increase of 565.2, making the final amount 925.2.
