Question

Вычислите 1) 16 3/13 - 6 8/13 2) 13 4/ 9 - 2 8/9 3) 10 7/16 - 4 12/16

Answer 1

16  3/13 - 6  8/13 = 15  16/13 - 6   8/13  = 9  8/13
13  4/9 - 2  8/9  = 12  13/9 - 2  8/9 = 10  5/9
10  7/16 - 4  12/16 = 9  23 / 16 - 4   12/16 = 5  11/16 

Answer 2

1)10 5/13 2)11 4/9 3)5 11/16

Answer 3

1) 16 3/13 - 6 8/13 First, we need to convert the mixed numbers to improper fractions: 16 3/13 = (16 * 13 + 3)/13 = 211/13 6 8/13 = (6 * 13 + 8)/13 = 86/13

Now we can subtract: 211/13 - 86/13 = 125/13

So, the answer is 125/13.

2) 13 4/9 - 2 8/9 First, we need to convert the mixed numbers to improper fractions: 13 4/9 = (13 * 9 + 4)/9 = 121/9 2 8/9 = (2 * 9 + 8)/9 = 26/9

Now we can subtract: 121/9 - 26/9 = 95/9

So, the answer is 95/9.

3) 10 7/16 - 4 12/16 First, we need to convert the mixed numbers to improper fractions: 10 7/16 = (10 * 16 + 7)/16 = 167/16 4 12/16 = (4 * 16 + 12)/16 = 76/16

Now we can subtract: 167/16 - 76/16 = 91/16

So, the answer is 91/16.
