Question

1 7/9 + 2 5/6 пжжжддддд

Answer 1

$1 \frac{7}{9} + 2 \frac{5}{6} = \frac{7}{9} + \frac{5}{3} = \frac{22}{9} = 2 \frac{4}{9}$

Answer 2

To add mixed numbers like 1 7/9 and 2 5/6, you need to convert them to improper fractions and then perform the addition.

Let's start by converting 1 7/9 into an improper fraction: 1 7/9 = (1 * 9 + 7) / 9 = 16/9

Next, let's convert 2 5/6 into an improper fraction: 2 5/6 = (2 * 6 + 5) / 6 = 17/6

Now that we have both fractions in improper form, we can add them: 16/9 + 17/6

To add fractions, we need a common denominator. The least common multiple (LCM) of 9 and 6 is 18.

Multiplying the numerator and denominator of the first fraction (16/9) by 2, we get: (16 * 2) / (9 * 2) = 32/18

The second fraction (17/6) doesn't need any changes since its denominator is already 6.

Now, we can add the fractions: 32/18 + 17/6

To add fractions with the same denominator, we add the numerators and keep the common denominator: (32 + 17) / 18 = 49/18

So, 1 7/9 + 2 5/6 is equal to 49/18 in improper fraction form.
