What is the portion if the base is 900 and the rate is 12¾ %?

To find the portion, you need to multiply the base (900) by the rate as a decimal.

To convert the rate from a mixed number to a decimal, you can follow these steps:
1. Convert the fraction part (¾) into a decimal. Divide the numerator (3) by the denominator (4): 3 ÷ 4 = 0.75.
2. Add the decimal to the whole number (12): 12 + 0.75 = 12.75.

Now that you have the rate as a decimal (12.75%), you can proceed with finding the portion.

Multiply the base (900) by the rate as a decimal (0.1275):
900 x 0.1275 = 114.75.

Therefore, the portion is 114.75.
