Answer 1

Відповідь:

$-3\frac{5}{6}$

Покрокове пояснення:

$-1\frac{3}{4} -2\frac{1}{12}=-\frac{7}{4} -\frac{25}{12} =-\frac{21}{12} -\frac{25}{12} =-\frac{46}{12} =-3\frac{10}{12} =-3\frac{5}{6}$

Answer 2

Ответ:

$-3\frac{5}{6}$

Пошаговое объяснение:

$-1\frac{3}{4} -2\frac{1}{12} = \frac{1*4+3}{4} - \frac{2*12+1}{12} = -\frac{7}{4} -\frac{25}{12} = -\frac{3*7}{3*4} - \frac{1*25}{1*12} -\frac{21}{12} - \frac{25}{12} = \frac{-21-25}{12} =-\frac{46}{12} = -\frac{23*2}{6*2} = -\frac{23}{6} = - 3\frac{5}{6}$

Ответ: $-3\frac{5}{6}$

Answer 3

To subtract the two fractions, -1 3/4 and 2 1/12, you'll need to convert them into improper fractions first. Here's the step-by-step solution:

Step 1: Convert the mixed numbers into improper fractions. -1 3/4 = -(4 * 1 + 3) / 4 = -7/4 2 1/12 = (12 * 2 + 1) / 12 = 25/12

Step 2: Subtract the fractions. -7/4 - 25/12

Step 3: Find a common denominator, which in this case is 12. Since 4 and 12 have a common multiple of 12, we can use it as the common denominator.

Step 4: Convert both fractions to have the common denominator of 12. -7/4 = -7 * 3/4 * 3 = -21/12 25/12 = 25 * 1/12 * 1 = 25/12

Step 5: Subtract the fractions. -21/12 - 25/12 = -(21 + 25)/12 = -46/12

Step 6: Simplify the fraction, if necessary. -46/12 can be simplified by dividing both the numerator and denominator by their greatest common divisor (GCD), which is 2. -46/12 = -23/6

So, the result of the subtraction -1 3/4 - 2 1/12 is -23/6 or -3 5/6.
