Answer 2

Ответ:

1 7/30

Пошаговое объяснение:

1) -3 7/15 + 5 2/5 = -3 7/15 + 5 6/15 = 1 14/15

2) 1 14/15 - 0,7 = 1 14/15 - 7/10 = 1 28/30 - 21/30 = 1 7/30

Answer 3

To simplify the expression, let's convert the mixed numbers to improper fractions first:

-3 = -3/1 7/15 = 7/15 -5 2/5 = -(5 + 2/5) = -5 - 2/5 = -25/5 - 2/5 = -27/5

Now, we can rewrite the expression:

-3/1 + (-7/10) - (-27/5)

Next, we'll simplify the expression by finding the common denominator, which is 10:

-30/10 + (-7/10) + (54/10)

Now, we can combine the numerators:

(-30 - 7 + 54)/10

Simplifying the numerator:

-37 + 54 = 17

Therefore, the final result is:

17/10
