Question

(-1,25+1 7/8):(-1 1/12- 0,5)=

Answer 1

(-1 1/4+1 7/8): (-1 1/12-1/2)=

(-1 2/8+1 7/8):(-1 1/12-6/12)=

5/8:(-1 7/12)=

5/8: (-19/12)=

- (5*12) /(8*19)=-15/38

Answer 2

У него все правильно будет :15/38

Answer 3

To solve the expression (-1.25 + 1 7/8) / (-1 1/12 - 0.5), you can follow these steps:

1. Convert the mixed numbers to improper fractions:

   • 1 7/8 = (8*1 + 7)/8 = 15/8
   • 1 1/12 = (12*1 + 1)/12 = 13/12

2. Perform the subtraction in the numerator and denominator:

   • Numerator: -1.25 + 15/8 = -10/8 + 15/8 = 5/8
   • Denominator: -13/12 - 0.5 = -13/12 - 6/12 = -19/12

3. Now, divide the numerator by the denominator: (5/8) / (-19/12)

To divide fractions, multiply by the reciprocal of the second fraction:

(5/8) * (-12/19)

Now, multiply the numerators and denominators:

(5 * -12) / (8 * 19) = -60/152

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

(-60/4) / (152/4) = -15/38

So, the result of the expression is -15/38.
