Question

Can you please answer so I already have the answers on the side if you can see but can you show me how he did it

Answer 1

What is 0.023% of 2100?

Word "is" means = and the word "of" means times

So it is x = 0.023% * 2100

At first, change 0.023% to a normal number by dividing it by 100

`x=(0.023)/(100)*2100`

Let us simplify the right side

`x=0.023*21`

Now use your calculator to find the answer

x = 0.483

0.483 is 0.023% of 2100
