Answer 2

Ответ:

Пошаговое объяснение:

(3/5-4/15)*(1/2-1/3) =1/18

3/5-4/15=9/15-4/15=5/15=1/3

1/2-1/3=3/6-2/6=1/6

1/3*1/6=1/18

10-5*1 1/5-1/3=3 2/3

5*1 1/5=5*6/5=6

10-6=4

4-1/3=3 2/3

Answer 3

Let's simplify the expressions step by step:

1. (3/5 - 4/15) * (1/2 - 1/3):

First, let's find the common denominator, which is 15, for both fractions: (3/5 - 4/15) * (1/2 - 1/3) = ((9/15) - (4/15)) * ((7/15) - (5/15))

Now, we can combine the fractions within the parentheses: = (5/15) * (2/15)

Finally, multiply the fractions: = (5 * 2) / (15 * 15) = 10 / 225

2. 10 - 5 * 1:

Perform the multiplication first: = 10 - 5 = 5

3. 1/5 - 1/3:

To subtract these fractions, we need a common denominator, which is 15: 1/5 = (3/15) and 1/3 = (5/15)

Now, we can subtract: (3/15) - (5/15) = -2/15

4. (1 1/5):

To convert this mixed number to an improper fraction, we multiply the whole number (1) by the denominator (5) and then add the numerator (1) to it: 1 1/5 = (5 * 1 + 1)/5 = 6/5

Now, let's put all the results together:

1. (3/5 - 4/15) * (1/2 - 1/3) = 10/225 = 2/45 (After simplification)

2. 10 - 5 * 1 = 5

3. 1/5 - 1/3 = -2/15

4. 1 1/5 = 6/5

Now, if you want to divide (2) by (3) and then subtract the result from (4):

(6/5) - (-2/15) = (6/5) + (2/15)

To add these fractions, we need a common denominator, which is 15: (6/5) = (18/15) and (2/15)

Now, we can add them: (18/15) + (2/15) = 20/15

The result is 20/15, which can be further simplified to 4/3.
