Answer 1

Ответ:

1)23/4-22/4=1/4

2)1/4+5/6=3/12+10/12=13/12

Answer 2

To solve the given expression, we need to perform the operations in the correct order, following the rules of arithmetic. Let's break it down step by step:

First, let's convert the mixed numbers to improper fractions:

2 3/4 = (2 * 4 + 3)/4 = 11/4 1 1/2 = (1 * 2 + 1)/2 = 3/2

Now, we can rewrite the expression:

2 3/4 - 1 1/2 + 5/6 = 11/4 - 3/2 + 5/6

Next, let's find a common denominator for the fractions involved. In this case, the least common multiple (LCM) of 4, 2, and 6 is 12. We'll rewrite the fractions with the denominator of 12:

11/4 = (11/4) * (3/3) = 33/12 3/2 = (3/2) * (6/6) = 18/12 5/6 = (5/6) * (2/2) = 10/12

Now, the expression becomes:

33/12 - 18/12 + 10/12

Next, we can combine the fractions:

33/12 - 18/12 + 10/12 = (33 - 18 + 10)/12 = 25/12

Therefore, the solution to the expression 2 3/4 - 1 1/2 + 5/6 is 25/12.
