Answer 3

Sure, I'll help you solve these math problems:

1. 3/4 + 1/11: To add fractions, you need to find a common denominator, which is the least common multiple (LCM) of the denominators. In this case, the LCM of 4 and 11 is 44.

Now, we convert both fractions to have a denominator of 44: (3/4) * (11/11) = 33/44 (1/11) * (4/4) = 4/44

Now, we add the two fractions together: 33/44 + 4/44 = 37/44

So, 3/4 + 1/11 = 37/44.

2. 3/8 * 2/5: To multiply fractions, simply multiply the numerators together and the denominators together:

(3/8) * (2/5) = (3 * 2) / (8 * 5) = 6/40

Now, we can simplify the fraction. Both the numerator and denominator have a common factor of 2: 6/40 = (6/2) / (40/2) = 3/20

So, 3/8 * 2/5 = 3/20.

3. (2 - 5/6) / (8/9): To divide fractions, you invert the divisor (the second fraction) and then perform multiplication:

(2 - 5/6) / (8/9) = (12/6 - 5/6) / (8/9) = (7/6) / (8/9)

Now, we can simplify the division by multiplying the first fraction by the reciprocal of the second fraction:

(7/6) * (9/8) = (7 * 9) / (6 * 8) = 63/48

Lastly, simplify the fraction: 63/48 = (63/3) / (48/3) = 21/16

So, (2 - 5/6) / (8/9) = 21/16.
