Question

A student multiplied a number by 4/8 instead of 8/4.What is the percentage error in the calculation?

Answer 1

Step-by-step explanation:

A student calculated the answer of 50 by multiplying X by 3/8, or 0.375. What would the correct answer (Y) be if X where to be divided by 0.375?

So, first things first is to find out X. This just requires dividing 50 by 0.375, which equals 133.3* (recurring). X = 133.3*.

Now, dividing 133.3 by 0.375 to reveal Y.

That would equal, and Y would be, 355.5*.

X = 133.3*

Y = 355.5*
