Answer:
A. 5 1/2 and D. 11/2
Step-by-step explanation:
Make improper fraction
8*1+3=11/8
Solve by multiplying:
4*11/8
44/8
Simplified is 11/2
We can turn it back into a mixed number
2*5+1=11 so 5 1/2
First, find the probability of each event:
1) the probability that the spinner will land on a 7.
Since the spinner is split 4 equal sections and there is only 1 sector with 7, we can say the probability of getting a 7 is 1/4 as there is only 1 of 7 out of the total of 4 sections.
<em>and</em>
2) the probability that the spinner will land on B.
Since the spinner is split into 3 equal sections, and there is only 1 sector for B, we can say the probability of getting B is 1/3.
To find the probability of 2 events, we need to multiply the two probabilities.
1/4*1/3 = 1/12
So the answer is 1/12.
Answer:

Answer:
15 girls
Explanation:
We know that the ratio of boys to girls in the classroom is 2:3, meaning that for every 2 boys there are 3 girls.
Now, we can set up a proportion to solve this problem.
