Answer 2

Ответ:

1)23

2)5,5

3)1,5

Пошаговое объяснение:

1) (3 1/5-1 2/3)*15= 1 8/15 * 15=23

2) (2 3/7+1 1/2):5/7= 3 13/14 : 5/7= 5 1/2= 5,5

3) (5 2/5+9 1/6):9 32/45= 14 17/30 : 9 32/45= 1 1/2= 1,5

Answer 3

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

1) Start by simplifying the expression within the first set of parentheses: (3 + 1/5 - 1 + 2/3) * 152

- Add the whole numbers: 3 - 1 = 2 - Add the fractions: 1/5 + 2/3 = (3/15 + 10/15) = 13/15

So, the expression within the first set of parentheses simplifies to: 2 + 13/15 = (2 * 15 + 13) / 15 = 43/15

2) Next, simplify the expression within the second set of parentheses: (2 + 3/7 + 1 + 1/2)

- Add the whole numbers: 2 + 1 = 3 - Add the fractions: 3/7 + 1/2 = (6/14 + 7/14) = 13/14

So, the expression within the second set of parentheses simplifies to: 3 + 13/14 = (3 * 14 + 13) / 14 = 55/14

3) Now, let's simplify the expression within the third set of parentheses: (5 + 2/5 + 9 + 1/6)

- Add the whole numbers: 5 + 9 = 14 - Add the fractions: 2/5 + 1/6 = (12/30 + 5/30) = 17/30

So, the expression within the third set of parentheses simplifies to: 14 + 17/30 = (14 * 30 + 17) / 30 = 437/30

4) Finally, divide the expression within the fourth set of parentheses: (437/30) : (9 + 32/45)

- Convert the whole number to a fraction: 9 = 9/1 - Add the fractions: 9/1 + 32/45 = (405/45 + 32/45) = 437/45

So, the expression within the fourth set of parentheses simplifies to: 437/30 : 437/45 = (437/30) * (45/437) = (437 * 45) / (30 * 437) = 45/30 = 3/2

5) Finally, multiply the results of the previous steps: (43/15) + (55/14) + (3/2)

- Find a common denominator for all the fractions: 2 * 14 * 15 = 420 - Convert each fraction to have the common denominator: - (43/15) * (28/28) = 1204/420 - (55/14) * (30/30) = 1650/420 - (3/2) * (210/210) = 315/420

So, the expression simplifies to: (1204/420) + (1650/420) + (315/420) = (1204 + 1650 + 315) / 420 = 3169/420

Therefore, the final answer to the given expression is 3169/420.
