Answer 1

Ответ:

$\frac{7}{72}$

Объяснение:

$\frac{1}{8} + \frac{2}{9} - \frac{1}{4} = \frac{9}{72} + \frac{16}{72} - \frac{18}{72} = \frac{7}{72}$

Answer 2

To solve the expression, we need to find a common denominator for the fractions involved, which in this case is 72. Then we can add and subtract the fractions accordingly. Here's the step-by-step solution:

1/8 + 2/9 - 1/4

Step 1: Convert the fractions to have a common denominator of 72.

1/8 = (1/8) * (9/9) = 9/72 2/9 = (2/9) * (8/8) = 16/72 1/4 = (1/4) * (18/18) = 18/72

Now the expression becomes:

9/72 + 16/72 - 18/72

Step 2: Add and subtract the fractions.

9/72 + 16/72 - 18/72 = (9 + 16 - 18) / 72 = 7/72

Therefore, the result of the expression 1/8 + 2/9 - 1/4 is 7/72.
