Answer:

1. A 2.D

Step-by-step explanation:

G is the number of girls who attended so that will be our product.

Since 75% of the girls attended the dinner and there are 12 girls on the team we are trying to find a part of the team that attended the dinner so

we would multiply a decimal times the whole.

Convert 75% into a decimal

$\frac{75}{100} = 0.75$

Multiply that by 12 to equal G

$0.75(12) = g$

So the answer is A

Kim pick 2 1/3 lbs every 1/4 hour. We are asked how many she pick every hour.

Let set up a fraction to make the equation equivalent

$\frac{2 \frac{1}{3} }{ \frac{1}{4} } = \frac{x}{1}$

1/4 goes into 1 4 times. so we would multiply 4 by 2 1/3 to find the x value.

$2\frac{1}{3} \times 4$

$2 \frac{1}{3} \times \frac{12}{3}$

$\frac{7}{3} \times \frac{12}{3}$

$\frac{84}{9}$

$9 \frac{3}{9}$

$9\frac{1}{3}$

so the answer is D
