Answer 2

Ответ:

35/57

Пошаговое объяснение:

1) 2 15/3 + 5 5/1 = 21/3 + 10/1 = 7 + 10 = 17

2) 8 20/19 + 2 16/3 = 9 1/19 + 7 1/3 = 9 3/57 + 7 19/57 = 16 22/57

3) 17 - 16 22/57 = 16 57/57 - 16 22/57 = 35/57

Answer 3

To solve the expression (2 15/3 + 5 5/1) - (8 20/19 + 2 16/3), you can follow these steps:

Step 1: Simplify each of the fractions within the parentheses.

2 15/3 = 2 * (15/3) = 2 * 5 = 10

5 5/1 = 5 * (5/1) = 5 * 5 = 25

8 20/19 = 8 * (20/19)

Now, let's find a common denominator for 3 and 19, which is 57.

So, (20/19) * (3/3) = (60/57)

2 16/3 = 2 * (16/3)

Now, let's find a common denominator for 3 and 57, which is 171.

So, (16/3) * (57/57) = (912/171)

Step 2: Rewrite the expression with the simplified fractions:

(10 + 25) - ((8 * 60/57) + (2 * 912/171))

Step 3: Continue simplifying within the parentheses:

(10 + 25) - ((480/57) + (1824/171))

Step 4: Find a common denominator for 57 and 171, which is 8559.

(10 + 25) - ((480 * 151/8559) + (1824 * 50/8559))

Step 5: Continue simplifying:

(35) - ((72580/8559) + (91200/8559))

Step 6: Combine the fractions within the parentheses:

(35) - (72580/8559 + 91200/8559)

Step 7: Find a common denominator and combine the fractions:

(35) - (163780/8559)

Step 8: Subtract the fractions:

(35 * 8559/8559) - (163780/8559)

Step 9: Subtract the numerators:

(299865/8559) - (163780/8559)

Step 10: Subtract the fractions:

(299865 - 163780)/8559

Step 11: Simplify the numerator:

135085/8559

Step 12: This fraction can be simplified further by finding the greatest common divisor (GCD) between the numerator and denominator:

GCD(135085, 8559) = 1

So, the fraction is already in its simplest form:

135085/8559

That's the final result of the expression: 135085/8559, which is an irreducible fraction.
