(2+1/15)-(1+37/90)=1-(1/15-37/90)

НОК(15, 90)=90

90/15=6

90/90=1

(6-37)/90=-31/90

1+(1/15-37/90)=1-31/90=59/90

Answer 3

To subtract the fractions 2 1/15 and 1 37/90, we need to convert them into improper fractions with a common denominator.

First, let's convert 2 1/15 into an improper fraction:

2 1/15 = (2 * 15 + 1) / 15 = 31/15

Now, let's convert 1 37/90 into an improper fraction:

1 37/90 = (1 * 90 + 37) / 90 = 127/90

Next, we need to find a common denominator for both fractions, which in this case is 90.

Now we can subtract the fractions:

31/15 - 127/90

To subtract fractions, we need to have a common denominator. Since both fractions have a denominator of 90, we can subtract the numerators directly:

(31 - 127) / 90 = -96/90

Finally, we can simplify the result by dividing both the numerator and denominator by their greatest common divisor (GCD), which in this case is 6:

-96/90 = (-16 * 6) / (15 * 6) = -16/15

Therefore, 2 1/15 - 1 37/90 is equal to -16/15.
