2. The hundredths model is shaded to represent a division

solniwko [45]

Answer:

Option D

Step-by-step explanation:

If the whole grid is considered to be 1,

Each small grid will value = $\frac{1}{100}=0.01$

There are 72 shaded grids which represent the hundreds = 0.72

When these grids have been divided into 9 equal rows, number of grids in each row = 8

And the value of 8 grids in each row = 0.01 × 8 = 0.08

So the equation is,

0.72 ÷ 9 = 0.08

Therefore, equation represented by the model will be Option (D).
