Decimals doubt

x and y are expressed as decimals. When (x+y) is rounded to hundredth decimal place, it is equal to x.

Quantity A- y
Quantity B- 0.007

Try an example.

I am stuck at what examples to take. Please help!

Let x = 2
y = 0.003

What happens then?

Ok understood. But I was not getting which numbers to plug in. Can you please provide some tips on this?
