Question

9 2/12-2 7/12 .............​

Answer 1

Ответ:

и так, чтобы от дроби отнять дробь, надо привести к общему знаменателю, но тк тут уже общий знаменатель есть, то просто отнимаем:

9 2/12 - 2 7/12 = 8 14/12 - 2 7/12= 6 7/12

ответ: 6 7/12

Answer 2

To subtract mixed numbers like $9 \frac{2}{12} - 2 \frac{7}{12}$, you can follow these steps:

Step 1: Convert both mixed numbers to improper fractions.

• $9 \frac{2}{12}$ can be converted to an improper fraction by multiplying the whole number (9) by the denominator (12) and then adding the numerator (2). So, $9 \frac{2}{12} = \frac{9 \cdot 12 + 2}{12} = \frac{108 + 2}{12} = \frac{110}{12}$.
• $2 \frac{7}{12}$ can be converted to an improper fraction in the same way: $2 \frac{7}{12} = \frac{2 \cdot 12 + 7}{12} = \frac{24 + 7}{12} = \frac{31}{12}$.

Step 2: Subtract the two improper fractions. $\frac{110}{12} - \frac{31}{12}$

Step 3: Since the denominators are the same, you can subtract the numerators directly. $\frac{110 - 31}{12} = \frac{79}{12}$

So, $9 \frac{2}{12} - 2 \frac{7}{12} = \frac{79}{12}$.
