Question

3 4/9 - 2 5/6 = ответ?

Answer 1

Ответ:

$\frac{11}{18}$

Пошаговое объяснение:

$3\frac{4}{9}-2\frac{5}{6}=3\frac{4*2}{9*2}-2\frac{5*3}{6*3}=3\frac{8}{18}-2\frac{15}{18}=(3-1)+\frac{8+18}{18}-2\frac{15}{18}=2\frac{26}{18}-2\frac{15}{18}=\frac{11}{18}$

Answer 2

$3 \frac{4}{9} - 2 \frac{5}{6} = \frac{3 \times 9 + 4}{9} - \frac{2 \times 6 + 5}{6} = \frac{31}{9} - \frac{17}{6} = \frac{31 \times 2}{9\times 2} - \frac{17 \times 3}{6 \times 3} = \frac{62}{18} - \frac{51}{18} = \frac{62 - 51}{18} = \frac{11}{18}$

Answer 3

To subtract mixed numbers, you need to perform the subtraction separately for the whole numbers and the fractions, and then combine the results. Here's how you can do it:

1. Subtract the whole numbers: 3 - 2 = 1

2. Subtract the fractions:

   • For the fractions 4/9 and 5/6, you need to have a common denominator. The least common multiple of 9 and 6 is 18.
   • Convert 4/9 to an equivalent fraction with a denominator of 18: (4/9) * (2/2) = 8/18
   • Convert 5/6 to an equivalent fraction with a denominator of 18: (5/6) * (3/3) = 15/18
   • Subtract the fractions: 8/18 - 15/18 = -7/18

Now combine the results:

1 (whole number part) - 7/18 (fractional part) = 1 - 7/18

You can leave it in this form, or simplify the fraction further if needed. The final result is approximately 1 - 0.3889, which is approximately 0.6111.
