How to model a decimal in a 10 by 10 grid?

In 1.42 = 1 42/100 or 1 + 42/100, there are two parts. They are 1 and 42/100. So, we have to use two 10 by-10 grids to model the decimal 1.42. Since we write 1.42 = 100/100 + 42/100, we have to shade all the 100 parts in the first grid and 42 parts in the second grid. Example 3 : Model 0.53 by shading a 10-by-10 grid. Solution :

How do you add decimals to a grid?

To arrange the decimals 9.870, 9.9, 9.7863, 9.86 in ascending order, first place them in a grid with the decimal points all lined up in the same column, and add zeros to decimals as needed so that all decimals have the same number of places (in this case, 4 places): 9.8700, 9.9000, 9.7863, 9.8600.

How do you multiply decimals on a decimal grid?

Multiplying decimals on the decimal grids is not as scary as it sounds. In fact, it is simple! Let’s look at the multiplication problem 0.4 x 0.5. First, we color in the first factor vertically. This means we will color in four-tenths or four out of ten columns. Next, we color in the next factor: five-tenths.
