Answer 2

Ответ: 1) 3/3 3/4=3:15/4=12/15=4/5.

2) 2 2/5-4/5=(12-4)/5=8/5.

3) 8/5-3 5/6=8/5-23/6=(8*1,2-23)/6=-13,4/6=-134/60=-67/30=-2 7/30.

Answer 3

To solve the expression $\frac{3}{4} + \frac{2}{5} - \frac{3}{6}$, we need to find a common denominator for the fractions and then perform the operations.

The least common multiple of 4, 5, and 6 is 60. Therefore, we can rewrite the fractions with a common denominator of 60:

$$\frac{3}{4} = \frac{3 \times 15}{4 \times 15} = \frac{45}{60}$$

$$\frac{2}{5} = \frac{2 \times 12}{5 \times 12} = \frac{24}{60}$$

$$\frac{3}{6} = \frac{3 \times 10}{6 \times 10} = \frac{30}{60}$$

Now the expression becomes:

$$\frac{45}{60} + \frac{24}{60} - \frac{30}{60}$$

Combine the fractions:

$$\frac{45 + 24 - 30}{60} = \frac{39}{60}$$

Now, the fraction $\frac{39}{60}$ can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 3:

$$\frac{39 \div 3}{60 \div 3} = \frac{13}{20}$$

So, $\frac{3}{4} + \frac{2}{5} - \frac{3}{6} = \frac{13}{20}$.
