Answer:
15/7
Step-by-step explanation:
To divide fractions, the process is as follows:
1) Flip one of the fractions over (numerator becomes denominator, denominator becomes numerator). In this problem, this step looks like:
5/7 divided by 1/3 ---> 5/7 divided by 3/1
2) Once one fraction is flipped, change the division sign to a multiplication sign. In this problem, this step looks like:
5/7 divided by 3/1 ---> 5/7 * 3/1
3) Multiply the fraction (multiply one fraction's numerator and denominator by the other's) In this problem, this step looks like:
5/7 * 3/1 ---> 15/7.
To check, use the same steps in the problem ? * 1/3 = 5/7. You'll find that 15/7 * 1/3 = 5/7.

Answer:
0.083
Step-by-step explanation:
To solve the above question, we use the combination method.
C(n, r) = nCr = n!/r!(n - r)!
Probability of answering (all 5 correctly)
= Probability of answering ( 5 out of 7 correctly)/ Probability of answering (5 out of 10 problems)
Probability of answering ( 5 out of 7 correctly) = 7C5
nCr = n!/r!(n - r)!
= 7!/5! (7 - 5)!
= 7 × 6 × 5 × 4 × 3 × 2 × 1/( 5 × 4 × 3 × 2 × 1) × (2 × 1)
= 21 ways
Probability of answering (5 out of 10 problems) = 10C5
nCr = n!/r!(n - r)!
= 10!/5! (10 - 5)!
= 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1/( 5 × 4 × 3 × 2 × 1) × (5 × 4 × 3 × 2 × 1)
= 252 ways
Probability of answering (all 5 correctly)
= 21/252
= 0.0833333333
Approximately = 0.083
