Question

3/5+14 8/15=? 7 7/11+61/2. 2 7/10+7 2/15​

Answer 1

Ответ:

1)$\frac{227}{15} =15\frac{2}{15}$ ; 2)$\frac{839}{22} =38\frac{3}{22}$ ; 3)$9\frac{5}{6}$

Пошаговое объяснение:

$1)\frac{3}{5} +14\frac{8}{15}$

$\frac{3}{5} + \frac{218}{15}$

$\frac{227}{15} =15\frac{2}{15}$

$2)7\frac{7}{11} +\frac{61}{2}$

$\frac{84}{11} + \frac{61}{2}$

$\frac{839}{22} =38\frac{3}{22}$

$3)2\frac{7}{10} +7\frac{2}{15}$

$(2+7)+(\frac{7}{10} + \frac{2}{15} )$

$9+\frac{5}{6}$

$9\frac{5}{6}$

Answer 2

Let's simplify these expressions step by step:

1. 3/5 + 14 8/15: First, convert the mixed number 14 8/15 into an improper fraction. 14 8/15 = 14 + 8/15 = (14 * 15/15) + 8/15 = 210/15 + 8/15 = 218/15

   Now, add 3/5 to 218/15: (3/5) + (218/15)

   To add these fractions, you need to find a common denominator, which in this case is 15: (3/5) * (3/3) + (218/15)

   Now the fractions have a common denominator: (9/15) + (218/15)

   Add the numerators together: 9 + 218 = 227

   So, 3/5 + 14 8/15 = 227/15

2. 7 7/11 + 61/2: First, convert the mixed number 7 7/11 into an improper fraction. 7 7/11 = 7 + 7/11 = (7 * 11/11) + 7/11 = 77/11 + 7/11 = 84/11

   Now, add 84/11 to 61/2: (84/11) + (61/2)

   To add these fractions, you need to find a common denominator, which in this case is 22: (84/11) * (2/2) + (61/2)

   Now the fractions have a common denominator: (168/22) + (61/2)

   Add the numerators together: 168 + 61 = 229

   So, 7 7/11 + 61/2 = 229/2

3. 2 7/10 + 7 2/15: First, convert both mixed numbers into improper fractions: 2 7/10 = 2 + 7/10 = (2 * 10/10) + 7/10 = 20/10 + 7/10 = 27/10 7 2/15 = 7 + 2/15 = (7 * 15/15) + 2/15 = 105/15 + 2/15 = 107/15

   Now, add 27/10 to 107/15: (27/10) + (107/15)

   To add these fractions, you need to find a common denominator, which in this case is 30: (27/10) * (3/3) + (107/15) * (2/2)

   Now the fractions have a common denominator: (81/30) + (214/30)

   Add the numerators together: 81 + 214 = 295

   So, 2 7/10 + 7 2/15 = 295/30

Now, you can simplify the fractions further if needed, but these are the results of the given additions.
