Question

Find the error in 135% of 40.

a. 0.125 x 40 = 5
b. 135% x 40 = 5
c. 135% of 40 is 54
d. There is no error in the expression.

Answer 1

The error is in option b, where 135% x 40 is incorrectly stated as equaling 5. The correct computation shows that 135% of 40 is equal to 54.

Step-by-step explanation:

To find the error in calculating 135% of 40, we need to convert the percentage to a decimal and then multiply it by the number. The correct calculation is as follows:

1. Convert 135% to a decimal, which gives 1.35.
2. Multiply 1.35 by 40.
3. The result is 54.

Option a, where 0.125 is multiplied by 40, is irrelevant to the problem at hand.

Regarding option b, 135% x 40 = 5 is incorrect because when the correct calculation is performed, as shown above, the result is 54, not 5.

Option c is correct as it correctly states that 135% of 40 is 54.

Option d, which claims there is no error in the expression, is incorrect because option b indeed contains an error.

Thus, the statement with an error is option b.
