Question

3 3/5+(-2 4/9)-(-1 11/15) =​

Answer 1

Ответ:

2$\frac{8}{9}$      

Пошаговое объяснение:

$\frac{18}{5} - 2\frac{4}{9} +1\frac{11}{15}$

$\frac{18}{5} -\frac{22}{9} +\frac{26}{15}$=$\frac{26}{9}$

Answer 2

To solve this expression, you can follow these steps:

Step 1: Convert mixed numbers to improper fractions.

• 3 3/5 as an improper fraction is 18/5.
• -2 4/9 as an improper fraction is -22/9.
• -1 11/15 as an improper fraction is -26/15.

Step 2: Perform the arithmetic operations.

So the expression becomes:

18/5 + (-22/9) - (-26/15)

Step 3: To subtract a negative number, you can change it to addition and reverse the sign.

18/5 + (-22/9) + 26/15

Step 4: Find a common denominator to add the fractions. The least common multiple (LCM) of 5, 9, and 15 is 45.

To make the denominators of all fractions 45, you need to multiply each fraction by the appropriate factor:

(18/5) * (9/9) = 162/45 (-22/9) * (5/5) = -110/45 (26/15) * (3/3) = 78/45

Now, the expression is:

(162/45) + (-110/45) + (78/45)

Step 5: Add the fractions with a common denominator:

(162/45) + (-110/45) + (78/45) = (162 - 110 + 78) / 45 = 130/45

Step 6: Simplify the fraction, if possible:

130/45 = 26/9

So, the result of the expression is 26/9 or 2 8/9 as a mixed number.
