Question

How to do the problem and for it to be explained

Answer 1

Shade in two blocks.
They are the same because 20 is a whole number. tenths are decimals. so one tenth is 0.1 . multiply the tenth by twenty, and you get 0.2 which on the grapgh is the same as 2 blocks

Answer 2

`(20)/(10)=2`

Explanation:

To answer this question, it is important to realize that one grid has 100 squares. In addition to this, 20/10 is a ratio and may be rewritten as 2. 20/10=2*100 squares is equal to 200 squares. So shade two grids, completely. Because 2 grids have 200 squares.
