Answer 1

Ответ:

=(55/12)*(-14/11)-(16/15)*(-45/64)=(-35/2)+3/4=3/4-70/4=-63/4=-16,75

Answer 2

Sure, let's solve the expression step by step:

Step 1: Convert mixed numbers to improper fractions 4 7/12 = (4 × 12 + 7) / 12 = 55 / 12 -1 3/11 = (-1 × 11 + 3) / 11 = -8 / 11 1 1/15 = (1 × 15 + 1) / 15 = 16 / 15

Step 2: Perform the multiplications 55 / 12 × (-8 / 11) = (55 × -8) / (12 × 11) = -440 / 1320 = -1/3 16 / 15 × (-45 / 64) = (16 × -45) / (15 × 64) = -720 / 960 = -3/4

Step 3: Perform the subtraction -1/3 - (-3/4) = -1/3 + 3/4

To add fractions, we need to find a common denominator. The least common multiple of 3 and 4 is 12.

-1/3 + 3/4 = (-1/3) × (4/4) + (3/4) × (3/3) = -4/12 + 9/12 = 5/12

So, the result of the expression is:

4 7/12 × (-1 3/11) - (1 1/15 × (-45/64)) = 5/12 or in mixed number form: 0 5/12
