Question

8 7/12-4 5/18-1 1/4 решите умоляю полностью

Answer 1

8 7/12 - 4 5/18 - 1 1/4=8 21/36 - 4 10/36 - 1 9/36=(8-4-1)+(21/36 - 10/36 - 9/36)=3+2/36=3+1/18=3 1/18

Answer 2

To solve the expression 8 + 7/12 - 4 + 5/18 - 1 + 1/4, we need to follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).

Let's break down the expression step by step:

1. First, we need to simplify the addition and subtraction of whole numbers: 8 - 4 - 1 = 3.

2. Next, we need to simplify the addition and subtraction of fractions. To do this, we need to find a common denominator for the fractions involved. In this case, the common denominator is 36 (12 * 3 = 36 and 18 * 2 = 36).

- 7/12 + 5/18 + 1/4 = (7 * 3)/(12 * 3) + (5 * 2)/(18 * 2) + 9/36 = 21/36 + 10/36 + 9/36 = (21 + 10 + 9)/36 = 40/36

3. Now, we have a mixed number (3) and an improper fraction (40/36). To add them together, we need to convert the mixed number to an improper fraction.

- 3 = 3/1

- 3/1 + 40/36 = (3 * 36)/(1 * 36) + 40/36 = 108/36 + 40/36 = (108 + 40)/36 = 148/36

4. Finally, we can simplify the fraction 148/36 by finding the greatest common divisor (GCD) of the numerator and denominator, and dividing both by the GCD.

- The GCD of 148 and 36 is 4.

- 148/36 = (148/4)/(36/4) = 37/9

Therefore, the solution to the expression 8 + 7/12 - 4 + 5/18 - 1 + 1/4 is 37/9.
