Question

1/2+1/4=? 1/6+1/2=? 1/3+2/9=? 3/4+3/8= ? 3/10+2/5=? 5/6+5/18=? 2/25+1/5=? 21/50+9/10=?

Answer 1

1/2+1/4=3/4 1/6+1/2=4/6 или 2/3 1/3+2/9=5/9 3/4+3/8=9/8 3/10+2/5=7/10 5/6+5/18=20/18 2/25+1/5=7/25 21/50+9/10=66/50

Answer 2

Let's solve each of the expressions step by step:

1. 1/2 + 1/4 = (1/2) + (1/4) = 2/4 + 1/4 = 3/4

2. 1/6 + 1/2 = (1/6) + (1/2) = 1/6 + 3/6 = 4/6 = 2/3

3. 1/3 + 2/9 = (1/3) + (2/9) = 3/9 + 2/9 = 5/9

4. 3/4 + 3/8 = (3/4) + (3/8) = 6/8 + 3/8 = 9/8 (Note: This result is improper, and you can convert it to a mixed number by dividing 9 by 8: 9 ÷ 8 = 1 with a remainder of 1, so it can be written as 1 1/8.)

5. 3/10 + 2/5 = (3/10) + (2/5) = 3/10 + 4/10 = 7/10

6. 5/6 + 5/18 = (5/6) + (5/18) = 15/18 + 5/18 = 20/18 (Note: This result is improper, and you can convert it to a mixed number by dividing 20 by 18: 20 ÷ 18 = 1 with a remainder of 2, so it can be written as 1 2/18. You can simplify the fraction: 1 2/18 = 1 1/9.)

7. 2/25 + 1/5 = (2/25) + (1/5) = 2/25 + 5/25 = 7/25

8. 21/50 + 9/10 = (21/50) + (9/10) = 21/50 + 25/50 = 46/50 (Note: This result is improper, and you can convert it to a mixed number by dividing 46 by 50: 46 ÷ 50 = 0 with a remainder of 46, so it can be written as 0 46/50. You can simplify the fraction: 0 46/50 = 0 23/25.)

So the results are:

1. 1/2 + 1/4 = 3/4
2. 1/6 + 1/2 = 2/3
3. 1/3 + 2/9 = 5/9
4. 3/4 + 3/8 = 1 1/8
5. 3/10 + 2/5 = 7/10
6. 5/6 + 5/18 = 1 1/9
7. 2/25 + 1/5 = 7/25
8. 21/50 + 9/10 = 0 23/25
