4/5+6/9;3/10+6/100;3/24+6/12;7/18+4/9;41/45+1/15;4/10+5/15;7/19+1/2;4/8+3:7 Помагите пожалуйста срочно!!!

Answer 1

4/5+6/9 = 36/45 +30/45 = 66/45 =22/15
3/10+6/100;30/100+6/100 = 36/100 = 9/25
3/24+6/12 = 3/24 +12/24 = 15/24 = 5/8
7/18+4/9=7/18 + 8/18 = 15/18 =5/6 
41/45+1/15=41/45 + 3/45 = 44/45
4/10+5/15= 12/30 + 10/30 = 22/30 = 11/15
7/19+1/2 = 14/38 + 19/38 = 33/38
4/8+3:7 = 28/56 + 24/56 = 52/56 =13/14

Calculation of Fractions

Let's calculate the given fractions:

1. 4/5 + 6/9: To add fractions, we need to find a common denominator. The least common multiple of 5 and 9 is 45. So, we can rewrite the fractions with a common denominator: - 4/5 = 36/45 - 6/9 = 30/45

Now, we can add the fractions: - 4/5 + 6/9 = 36/45 + 30/45 = 66/45

Therefore, 4/5 + 6/9 = 66/45.

2. 3/10 + 6/100: To add fractions, we need to find a common denominator. The least common multiple of 10 and 100 is 100. So, we can rewrite the fractions with a common denominator: - 3/10 = 30/100 - 6/100 = 6/100

Now, we can add the fractions: - 3/10 + 6/100 = 30/100 + 6/100 = 36/100

Therefore, 3/10 + 6/100 = 36/100.

3. 3/24 + 6/12: To add fractions, we need to find a common denominator. The least common multiple of 24 and 12 is 24. So, we can rewrite the fractions with a common denominator: - 3/24 = 3/24 - 6/12 = 12/24

Now, we can add the fractions: - 3/24 + 6/12 = 3/24 + 12/24 = 15/24

Therefore, 3/24 + 6/12 = 15/24.

4. 7/18 + 4/9: To add fractions, we need to find a common denominator. The least common multiple of 18 and 9 is 18. So, we can rewrite the fractions with a common denominator: - 7/18 = 7/18 - 4/9 = 8/18

Now, we can add the fractions: - 7/18 + 4/9 = 7/18 + 8/18 = 15/18

Therefore, 7/18 + 4/9 = 15/18.

5. 41/45 + 1/15: To add fractions, we need to find a common denominator. The least common multiple of 45 and 15 is 45. So, we can rewrite the fractions with a common denominator: - 41/45 = 41/45 - 1/15 = 3/45

Now, we can add the fractions: - 41/45 + 1/15 = 41/45 + 3/45 = 44/45

Therefore, 41/45 + 1/15 = 44/45.

6. 4/10 + 5/15: To add fractions, we need to find a common denominator. The least common multiple of 10 and 15 is 30. So, we can rewrite the fractions with a common denominator: - 4/10 = 12/30 - 5/15 = 10/30

Now, we can add the fractions: - 4/10 + 5/15 = 12/30 + 10/30 = 22/30

Therefore, 4/10 + 5/15 = 22/30.

7. 7/19 + 1/2: To add fractions, we need to find a common denominator. The least common multiple of 19 and 2 is 38. So, we can rewrite the fractions with a common denominator: - 7/19 = 14/38 - 1/2 = 19/38

Now, we can add the fractions: - 7/19 + 1/2 = 14/38 + 19/38 = 33/38

Therefore, 7/19 + 1/2 = 33/38.

8. 4/8 + 3:7: To add fractions, we need to find a common denominator. The least common multiple of 8 and 7 is 56. So, we can rewrite the fractions with a common denominator: - 4/8 = 28/56 - 3:7 = 24/56

Now, we can add the fractions: - 4/8 + 3:7 = 28/56 + 24/56 = 52/56

Therefore, 4/8 + 3:7 = 52/56.
