Question

Ariana shaded parts of the hundredths model below to represent the product of two numbers . Which equation does the model represent?

Answer 1

`0.4 * 0.8 = 0.32`

Explanation:

Given

See attachment for model

Required

The equation of the model

Let the vertical and the horizontal shades be represented as x and y

On the vertical axis, 40 boxes are shaded.

So;

`x = (40)/(100)`

On the horizontal axis, 80 boxes are shaded.

So;

`y = (80)/(100)`

So, the equation is:

`x * y`

This gives:

`(40)/(100) * (80)/(100)`

Express as decimal

`0.4 * 0.8`

Solve:

`0.4 * 0.8 = 0.32`

Hence, the equation is:

`0.4 * 0.8 = 0.32`
