Answer 1

Ответ:

1)-1 1/15÷4 4/5=-16/15:24/5=-16/15*5/24=-80/360= -2/9 ( скоротити на 40)

2)-1÷1 15/16= -1:31/16=-16/31 (При діленні одиниці на дріб, дріб перевертають; чисельник стає знаменником а знаменник чисельником)

Answer 2

Ответ:
1) = - 16/15 : 24/5 = -16/15 • 5/24 = - 2/9 (5 и 15 сокращаем на 5; 16 и 24 сокращаем на 8)
2) = -1 : 31/16 = -1 • 16/31 = - 16/31

Answer 3

1) -1 + 1/15 ÷ 4 + 4/5

First, let's simplify the fraction 1/15 ÷ 4. To do this, we multiply the numerator by the reciprocal of the denominator: 1/15 ÷ 4 = 1/15 × 1/4 = 1/60

Now we can rewrite the expression: -1 + 1/60 + 4/5

Next, we need to find a common denominator for 1/60 and 4/5. The least common multiple of 60 and 5 is 60, so we can rewrite the fractions with this denominator: -1 + 1/60 + 48/60

Now we can add the fractions: -1 + 49/60

To add the whole number -1, we can rewrite it as a fraction with the same denominator: -60/60 + 49/60 = -11/60

So the final answer is -11/60.

2) -1 ÷ 1 + 15/16

First, we can simplify -1 ÷ 1 to -1: -1 + 15/16

Now, we need to find a common denominator for -1 and 15/16. The least common multiple of 1 and 16 is 16, so we can rewrite the fractions with this denominator: -16/16 + 15/16

Now we can add the fractions: -1/16

So the final answer is -1/16.
