Answer 1

Ответ:

Пошаговое объяснение:

1) 6-3 4/9 =2 5/9

2)9 5/12- 7/12 =8 10/12=8 5/6

Answer 2

6-3 4/9=5 9/9-3 4/9=2 5/9;

9 5/12-7/12=8 17/12-7/12=8 10/12=8 5/6

Answer 3

To solve the given fractions, follow these steps:

1. $6 - \frac{3}{9}$

Step 1: Simplify the fraction $\frac{3}{9}$: The greatest common divisor (GCD) of 3 and 9 is 3. Divide both the numerator and denominator by 3 to get $\frac{1}{3}$.

Step 2: Subtract the simplified fraction from 6: $6 - \frac{1}{3} = \frac{18}{3} - \frac{1}{3} = \frac{18 - 1}{3} = \frac{17}{3}$

So, the result is $\frac{17}{3}$ or $5\frac{2}{3}$.

2. $9\frac{5}{12} - \frac{7}{12}$

The whole number part doesn't affect the subtraction of fractions, so we can deal with only the fractional part first:

Step 1: Subtract the fractions: $9\frac{5}{12} - \frac{7}{12} = 9\frac{5-7}{12} = 9\frac{-2}{12}$

Step 2: Simplify the fraction $\frac{-2}{12}$: The GCD of -2 and 12 is 2. Divide both the numerator and denominator by 2 to get $\frac{-1}{6}$.

Step 3: Rewrite the result: $9\frac{-1}{6}$

If we want to write this as a mixed number:

Step 4: Divide the numerator (-1) by the denominator (6): $-1 \div 6 = -\frac{1}{6}$

Step 5: Rewrite the mixed number: $9 - \frac{1}{6} = 8\frac{5}{6}$

So, the result is either $9\frac{-1}{6}$ or $8\frac{5}{6}$. Both forms are correct, but the latter is a mixed number.
