Answer 3

Let's calculate the expressions step by step:

1. 3/4 : 5/6 * 1/3: To divide fractions, we multiply by the reciprocal of the second fraction. So, 3/4 divided by 5/6 is equal to 3/4 multiplied by 6/5, which gives us:

(3/4) * (6/5) * (1/3) = (3 * 6 * 1) / (4 * 5 * 3) = 18/60 = 3/10

Therefore, 3/4 : 5/6 * 1/3 is equal to 3/10.

2. 3/5 + 4/7 + 1/8: To add fractions, we need to find a common denominator. The least common denominator for 5, 7, and 8 is 280. We can then convert each fraction to have a denominator of 280:

(3/5) * (56/56) = 168/280 (4/7) * (40/40) = 160/280 (1/8) * (35/35) = 35/280

Now, we can add the fractions:

168/280 + 160/280 + 35/280 = (168 + 160 + 35) / 280 = 363/280

Therefore, 3/5 + 4/7 + 1/8 is equal to 363/280.
