Question

В) 1 11/15 - 11/15 = ? г) 1 11/15 - 13/15 = ?

Answer 1

в) 1 11/15 - 11/15 = 1

г) 1 11/15 - 13/15 = (11+15)/15 - 13/15 = 26/15 - 13/15 = 13/15

Answer 2

а) To subtract fractions, you need to have a common denominator. In this case, the common denominator is 15.

1 11/15 can be rewritten as (15/15 + 11/15) = 26/15.

So, the calculation becomes:

26/15 - 11/15 = (26 - 11)/15 = 15/15 = 1.

Therefore, 1 11/15 - 11/15 = 1.

б) Again, we need to find a common denominator, which is 15.

1 11/15 can be rewritten as (15/15 + 11/15) = 26/15.

So, the calculation becomes:

26/15 - 13/15 = (26 - 13)/15 = 13/15.

Therefore, 1 11/15 - 13/15 = 13/15.
