Пошаговое объяснение:

(9 7/12 - 8 11/12) : 2/9 = 9 7/12 - 8 11/12 = 8/12 : 2/9 = 8/12 * 9/2 = 4/4(то есть 1) * 3/1(то есть 3) = 1*3 = 3

Answer 2

$9\frac{7}{12} -8\frac{11}{12} =8 \frac{19}{12} -8\frac{11}{12}= \frac{8}{12} } \\\\\\\frac{8}{12} : \frac{2}{9} = \frac{8}{12} * \frac{9}{2} =3$

Answer 3

To divide the mixed numbers (9 7/12 - 8 11/12) by the fraction 2/9, you can follow these steps:

Step 1: Convert the mixed numbers to improper fractions. 9 7/12 can be written as (12 * 9 + 7)/12 = 115/12. 8 11/12 can be written as (12 * 8 + 11)/12 = 107/12.

Step 2: Subtract the fractions. 115/12 - 107/12 = (115 - 107)/12 = 8/12.

Step 3: Simplify the fraction, if possible. Both the numerator and denominator are divisible by 4, so we can simplify further: 8/12 = (8/4) / (12/4) = 2/3.

Step 4: Divide the simplified fraction by 2/9. To divide fractions, we multiply the first fraction by the reciprocal of the second fraction. So, we have (2/3) * (9/2) = (2 * 9) / (3 * 2) = 18/6.

Step 5: Simplify the resulting fraction. Both the numerator and denominator are divisible by 6, so we can simplify further: 18/6 = (18/6) / (6/6) = 3/1 = 3.

Therefore, (9 7/12 - 8 11/12) divided by 2/9 is equal to 3.
