Step-by-step explanation:
5/6 and 3/8 - Get the multiples of 6: 6, 12, 18, 24, Multiples of 8: 8, 16, 24, 32.

Answer for LCD of fractions 1/2 and 3/5: 10, or C
This one is a bit easier - just find multiples of 5 that are even. The least one is 10.
Answer for LCD of fractions 1/12 and 3/4: 12, or B
Explanation: Multiples of 12 that are multiples of 4 but the least of them: 12.
A 95% confidence interval on the z-table is 1.96.
Now find the standard error using the formula: standard deviation / square root sample size:
0.7 / √100 = 0.07
Multiply to the confidence interval: 1.96 x 0.07 = 0.137 = 0.14
Now add and subtract tot he average weight:
14 - 0.14 = 13.86
14 + 0.14 = 14.14
The answer is 13.96 ≤ u ≤ 14.14
or -0.375
