Question

Обчисліть −1/8+(−2/9)=

Answer 1

- 1/8 + (-2/9) = - 9/72 - 16/72 = - 25/72.

Answer 2

To compute the sum of two fractions, −1/8 and (−2/9), you'll need to find a common denominator and then add the fractions together.

The common denominator for 8 and 9 is 72 (the least common multiple of 8 and 9). Now, let's convert both fractions to have a denominator of 72:

−1/8 = −9/72 (multiplied numerator and denominator by 9) −2/9 = −16/72 (multiplied numerator and denominator by 8)

Now, add the two fractions together:

−9/72 + (−16/72) = −25/72

So, the result of −1/8 + (−2/9) is −25/72.
