Answer 1

Ответ:

1/4 + (-0,25)+(-19/49)= - 19/49

1) переводим -0,25 = - 1/4

2) 1/4 - 1/4 - 19/49 = - 19/49

Answer 2

To add these fractions, you need to find a common denominator and then add the fractions together:

1/4 + (-0.25) + (-19/49)

First, let's express -0.25 as a fraction with a common denominator of 49:

-0.25 = -25/100 = -49/196

Now, we have the fractions with a common denominator:

1/4 + (-49/196) + (-19/49)

To add these fractions, you need to find a common denominator. In this case, the common denominator is 196 (the least common multiple of 4 and 49). You can rewrite the fractions with the common denominator:

(49/196) + (-49/196) + (-76/196)

Now, you can add the fractions together:

(49/196 - 49/196 - 76/196)

49/196 minus 49/196 is 0, so you're left with:

-76/196

You can simplify this fraction by dividing both the numerator and denominator by their greatest common divisor, which is 4:

-76 ÷ 4 / 196 ÷ 4 = -19/49

So, 1/4 + (-0.25) + (-19/49) is equal to -19/49.
