53/36,3/20

Пошаговое объяснение:

20/36+6/36+27/36=53/36

5/20+4/20-6/20=3/20

Answer 3

To simplify the given expressions, let's find the common denominator for each expression and then perform the additions/subtractions.

Expression 1: 5/9 + 1/6 + 3/4

To find the common denominator, we need to find the least common multiple (LCM) of 9, 6, and 4, which is 36.

Now, let's convert each fraction to have a denominator of 36:

5/9 = (5/9) * (4/4) = 20/36 1/6 = (1/6) * (6/6) = 6/36 3/4 = (3/4) * (9/9) = 27/36

Now, we can add the fractions:

20/36 + 6/36 + 27/36 = (20 + 6 + 27)/36 = 53/36

So, the simplified value of the first expression is 53/36.

Expression 2: 1/4 + 1/5 - 3/10

To find the common denominator, we need to find the least common multiple (LCM) of 4, 5, and 10, which is 20.

Now, let's convert each fraction to have a denominator of 20:

1/4 = (1/4) * (5/5) = 5/20 1/5 = (1/5) * (4/4) = 4/20 3/10 = (3/10) * (2/2) = 6/20

Now, we can add/subtract the fractions:

5/20 + 4/20 - 6/20 = (5 + 4 - 6)/20 = 3/20

So, the simplified value of the second expression is 3/20.

Therefore, the simplified values of the given expressions are:

1. 5/9 + 1/6 + 3/4 = 53/36
2. 1/4 + 1/5 - 3/10 = 3/20
