Покрокове пояснення:

3/12+25/30=3/12+5/6=$\frac{3+10}{12}=13/12=1\frac{1}{12}$

30/54+22/30=5/9+11/15=$\frac{25+33}{45}=\frac{58}{45}=1\frac{13}{45}$

Answer 2

To add the fractions 3/12 and 25/30, you first need to find a common denominator. In this case, the common denominator would be 60 because it's the least common multiple of 12 and 30.

Now, you need to express both fractions with this common denominator:

3/12 = (3/12) * (5/5) = 15/60 25/30 = (25/30) * (2/2) = 50/60

Now that both fractions have the same denominator, you can add them:

15/60 + 50/60 = (15 + 50)/60 = 65/60

So, 3/12 + 25/30 = 65/60.

You can simplify this fraction by dividing both the numerator and denominator by their greatest common divisor, which is 5:

(65 ÷ 5) / (60 ÷ 5) = 13/12

So, the simplified result is 13/12.
