Пошаговое объяснение:

4 3/4 : 1/4 - 1 5/6 • 3 = 13 1/2.

1) 4 3/4 : 1/4 = 19/4 • 4/1 = 19/1 = 19;

2) 1 5/6 • 3 =11/6 • 3/1 = (11•1)/2 = 5 1/2;

3) 19 - 5 1/2 = 18 2/2 - 5 1/2 = 13 1/2.

Answer 2

Ответ:

(19/4:1/4)-(11/6*3)=

1)19/4*4/1=19

2)11/6*3=11/2

Answer 3

To solve the expression, let's break it down step by step:

Step 1: Perform the operations inside the parentheses first. 1/4 - 1 5/6 * 3

Step 2: Multiply the whole number by the denominator and add the numerator to get an improper fraction for 1 5/6. 1 * 6 + 5 = 6 + 5 = 11 The improper fraction is 11/6.

Step 3: Now, multiply the result from Step 2 by 3. 11/6 * 3 = 33/6

Step 4: Convert the improper fraction back to a mixed number. 33/6 can be simplified to 5 3/6, and then further simplified to 5 1/2.

Step 5: Now, solve the subtraction. 1/4 - 5 1/2

Step 6: Convert 1/4 to the same denominator as 1/2, which is 2/8. 1/4 - 5 4/8

Step 7: Subtract the fractions. 1/4 - 5 4/8 = 1/4 - 4/8 = 1/4 - 1/2

Step 8: Find a common denominator, which is 4/8, for 1/4 and 1/2. 1/4 - 1/2 = 2/8 - 4/8

Step 9: Perform the subtraction of the fractions. 2/8 - 4/8 = -2/8

Step 10: Simplify the fraction. -2/8 can be simplified to -1/4.

So, the final result is: 4 3/4 : 1/4 - 1 5/6 * 3 = -1/4.
