Question

Calculate 5% of 88.5?

Answer 1

Answer:

4.425

Step-by-step explanation:

We need to change 5 % to a decimal.  Move the decimal two places to the left

.05  is 5% in decimal form

5% of 88.5

.05* 88.5

4.425

Answer 2

5% is just another way of writing 5/100

So we have 5/100 of 88.5 → 5100×88.5

This is the same as 5×88.5/100=5×0.885

But 5 is 1/2×10

So we can write 5×0.885 as 1/2×10×0.885

=1/2×8.85=4.425

hope it helps!
