A hockey goalie loses 2 3/5 rating points each time his team loses. If his team loses 8 games in a row, what number represents t

adelina 88 [10]

Answer:

$20\frac{4}{5}$

Step-by-step explanation:

We have been given that a hockey goalie loses 2 3/5 rating points each time his team loses. His team loses 8 games in a row.

To find the number that will represent the change in goalie's ratings after losing 8 games we will multiply 8 by $2\frac{3}{5}$ .

$8*(2\frac{3}{5})$

Let us convert our mixed fraction into improper fraction.

$8*\frac{13}{5}$

$\frac{8*13}{5}$

$\frac{104}{5}$

$20\frac{4}{5}$

Therefore, $20\frac{4}{5}$ will represent the change in the goalie's rating points.
