Question

Three girls cut out decimal models of hundredths. Amber doesn't shade any of her models. Grace qualifies three fifths of a model. Marsha shades one model and seven-tenths of another model. What decimal represents the number of shadows of each girl? Click on the icon to view the decimal models of hundredths. The decimal represents the number of shades of amber. The decimal represents the quantity that represents the quantity that Marsha qualifies. Tones of grace. The decimal (write whole numbers or decimals).

Answer 1

`Amber = 0`

`Grace = 0.60`

`Marsha =1.70`

Explanation:

Given

Decimal Grid = Hundredths

`Amber = None`

`Grace = (3)/(5)th`

`Marsha = 1 + (7)/(10)th`

To solve for each:

We have:

For Amber:

`Amber = 0 * 100`

`Amber = 0`

For Grace:

`Grace = (3)/(5)th`

`Grace = (3)/(5) * 100`

`Grace = (300)/(5)`

`Grace = 60`

This means that Grace shaded 60 of the hundredth models.

Decimal shaded is:

`Grace = 60 * (1)/(100)`

`Grace =(60)/(100)`

`Grace = 0.60`

For Marsha:

`Marsha = 1 + (7)/(10)th`

`Marsha = (10 + 7)/(10)th`

`Marsha = (17)/(10)th`

`Marsha = 1.7th`

Multiply this by 100, to get the number of shaded

`Marsha = 1.7 * 100`

`Marsha = 170`

This means that Marsha shaded 170 of the hundredth models.

Decimal shaded is:

`Marsha = (170)/(100)`

`Marsha =1.70`
