Answer 1

2 3/4 : 1 1/2 = 11/4 : 3/2 = (11*2) / (4*3) = 11/6 = 1 5/6

Answer 2

2 целых 3/4=11/4
1 целая 1/2=3/2
(11/4) : (3/2)=(11/4) * (2/3)=11/6=1 целая 5/6

Answer 3

Calculation

To solve the expression 2 + 3/4 : 1 + 1/2, we need to follow the order of operations, which is parentheses, multiplication and division (from left to right), and addition and subtraction (from left to right).

1. First, let's simplify the division: 3/4 : 1. The division of two fractions can be simplified by multiplying the first fraction by the reciprocal of the second fraction. In this case, the reciprocal of 1 is 1 itself. So, 3/4 : 1 = 3/4 * 1 = 3/4.

2. Now, let's simplify the addition: 2 + 3/4. To add a whole number and a fraction, we need to convert the whole number into a fraction with the same denominator as the fraction. In this case, the denominator is 4. So, 2 = 2/1 = 8/4. Now we can add the fractions: 8/4 + 3/4 = 11/4.

3. Finally, let's add the results of the previous steps: 11/4 + 1/2. To add fractions with different denominators, we need to find a common denominator. In this case, the common denominator is 4. So, we need to convert 1/2 into a fraction with a denominator of 4: 1/2 = 2/4. Now we can add the fractions: 11/4 + 2/4 = 13/4.

Therefore, the result of the expression 2 + 3/4 : 1 + 1/2 is 13/4.

Answer

The result of the expression 2 + 3/4 : 1 + 1/2 is 13/4.
