Answer:
3 3/4
Step-by-step explanation:
Dividing two fractions is the same as multiplying the first fraction by the reciprocal of the second fraction. so all you have to do is 5/3 x 9/4. Once you get the answer simplify it down to a mixed number or leave it as an improper fraction, i simplified down and got 3 3/4
Please mark as brainliest :)
I believe this is the way to solve it.
22 - 2 = 20
20 is 90.9% of 22
So the probability of choosing a student with a sibling at random should be 90.9% (or you can round up to 91%)
I hope this helps :)
Answer:
-10.5 deg
Step-by-step explanation:
