Answer :

To determine what number 110% of 90 is, follow these steps:

1. Understand the Percentage: The percentage we are working with is 110%.

2. Convert the Percentage to a Decimal: Converting a percentage to a decimal involves dividing by 100. Therefore, 110% can be converted to a decimal by performing the following calculation:
[tex]\[ 110\% = \frac{110}{100} = 1.1 \][/tex]

3. Multiply by the Base Number: Now, take the decimal value we obtained (1.1) and multiply it by the base number, which is 90. This is because finding a percentage of a number involves multiplying the decimal form of the percentage by the number.

So, we calculate:
[tex]\[ 1.1 \times 90 \][/tex]

4. Calculate the Result: Performing the multiplication gives us:
[tex]\[ 1.1 \times 90 = 99 \][/tex]

Therefore, 110% of 90 is 99.
