Answer 2

Ответ:

4/7

Пошаговое объяснение:

1) 6 5/6 : 1 5/36 = 41/6 : 41/36= (41 * 36)/(6 * 41) =6

2) 8 5/7 - 6 = 2 5/7

3) 2 5/7 : 4 3/4 = 19/7 : 19/4 = (19*4)/(7*19)=4/7

Answer 3

To solve this expression, you can follow these steps:

Step 1: Convert all mixed numbers to improper fractions. Step 2: Perform the division inside the parentheses. Step 3: Divide the result from Step 2 by 4 3/4.

Let's begin with Step 1:

8 5/7 as an improper fraction: (7 * 8 + 5) / 7 = 61/7 6 5/6 as an improper fraction: (6 * 6 + 5) / 6 = 41/6 1 5/36 as an improper fraction: (36 * 1 + 5) / 36 = 41/36

Now, let's move on to Step 2:

(61/7 - 41/6) ÷ (41/36)

To divide fractions, you can multiply by the reciprocal of the second fraction:

(61/7 - 41/6) * (36/41)

Now, perform the subtraction:

[(61 * 36) / (7 * 1) - (41 * 36) / (6 * 1)] / 41

(2196/7 - 2466/6) / 41

To simplify the fractions, find a common denominator:

(2196/7 - 2466/7) / 41

Now, subtract the fractions:

(2196 - 2466) / 7 / 41

-270 / 7 / 41

Now, let's move on to Step 3:

To divide by a fraction, you can multiply by its reciprocal:

(-270/7) * (1/41)

Multiply the numerators and denominators:

(-270 * 1) / (7 * 41)

-270 / 287

Now, you can simplify the fraction. Both the numerator and denominator have a common factor of 9:

(-30 / 41)

So, the final result is:

-30/41
