Julian has 56 books arranges them in seven groups. Julian buys 16 more books and groups them in the same way as his other books.

Sunny_sXe [5.5K]

The equation that would represent the number of groups in al would be:

(56/8) + (16/8) = g
7 + 2 = g
9 = g

There would be 9 groups.

You will use the information to write a number sentence that would show the total number of groups.

For both of these, we will divide the wanted outcome by the number of possible outcomes. We will end up with a decimal. A decimal multiplied by 100 becomes a percent.

[a] 50%

$\displaystyle \frac{\text{wanted outcomes}}{\text{possible outcomes}} =\frac{\text{student failed}}{\text{Period 2's class}} =\frac{12}{24} =0.5,\:0.5*100=50\%$

[b] 52%

$\displaystyle \frac{\text{wanted outcomes}}{\text{possible outcomes}} =\frac{\text{student failed from Period 3}}{\text{fails from both classes}} =\frac{13}{25} =0.52,$

$\displaystyle 0.52*100=52\%$
