Answer 2

Let's break down the calculations step by step:

1. Subtracting fractions: 3/4 - 1/3 To subtract fractions, we need a common denominator. In this case, the common denominator is 12. Converting 3/4 to have a denominator of 12: (3/4) * (3/3) = 9/12 Converting 1/3 to have a denominator of 12: (1/3) * (4/4) = 4/12

Now we can subtract: 9/12 - 4/12 = 5/12

Therefore, 3/4 - 1/3 is equal to 5/12.

2. Multiplying fractions: 4/5 * 15 To multiply fractions, we simply multiply the numerators and denominators. 4/5 * 15/1 = (4 * 15) / (5 * 1) = 60/5

Simplifying the fraction: 60/5 = (60/5) / (5/5) = 12/1 = 12

Therefore, 4/5 multiplied by 15 is equal to 12.

I hope this helps clarify the calculations for you!
