1 volunteer - 4 h - 48 calls
12 volunteers - 4 h - x calls
The time is the same, so it's irrelevant.
1 volunteer - 48 calls
12 volunteers - x calls
x=12*48=576
So it's 576 hours.

Answer: Fact families are 3 numbers that make up a set of related math facts
Step-by-step explanation:
.An example of a fact family for multiplication and division is 2, 3, and 6: 2 X 3 = 6, 3 X 2 = 6, 6 2 = 3, and 6 3 = 2.
Answer:
1. 1/3 * 7 = 7/3 = 2 1/3 or two and one-third
2. 7/9 * 3/5 = (3*7)/(9*5) = 21/45
dividing numerator and denominator by 3
21/45 = 7/15 or start fraction seven over fifteen end fraction
3. 2 2/3 is equivalent to 8/3, then:
8/3 * 9 = 8 * 9/3 = 8 * 3 = 24
4. -4 1/2 is equivalent to -9/2
-2 1/3 = -7/3
Then:
-4 1/2 * (-2 1/3) = -9/2 * (-7/3) = -3/2 * (-7) = 21/2 = 10 1/2 or 10 one-half
5. (1/3) / (5/6) = 1/3 * 6/5 = 2/5 or two-fifths
6. 3 1/5 is equal to 16/5
16/5 ÷ 8 = 16/5 * 1/8 = 16/8 * 1/5 = 2 * 1/5 = 2/5 or The fraction is 2 over 5.
7. (-3/5) / (-3/4) = -3/5 * (-4/3) = 12/15
dividing each term by 3:
4/5 or The fraction is 4 over 5.
8. -3 1/5 si equivalent to -16/5
-3 1/5 ÷ 2/15 = -16/5 * 15/2 = -16/2 * 15/5 = -8 * 3 = -24
Sorry but the picture is blurry so I can’t help you but maybe I could help you if you showed me the pic again thx
