Question

Обчисліть: −1/8+(−2/9)=

Answer 1

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

Answer 2

To compute the sum of these two fractions, you need to find a common denominator and then add the numerators.

The common denominator for -1/8 and -2/9 is the least common multiple (LCM) of 8 and 9, which is 72.

Now, we need to convert both fractions to have a denominator of 72:

-1/8 = (-1 * 9) / (8 * 9) = -9 / 72 -2/9 = (-2 * 8) / (9 * 8) = -16 / 72

Now, add the fractions:

-9/72 + (-16/72) = (-9 - 16) / 72 = -25/72

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