Question

-2 33/66 + 8 56/64 как решить????

Answer 1

$-2 \frac{33}{66} + 8\frac{56}{64}=-2 \frac{1}{2} + 8\frac{7}{8}=-2 \frac{4}{8} + 8\frac{7}{8}=6\frac{3}{8}$

Answer 2

To solve the expression, you need to perform addition and simplification of the mixed numbers (a mixed number is composed of a whole number and a fraction).

Step 1: Convert the mixed numbers to improper fractions (fractions where the numerator is greater than the denominator):

-2 = -2/1 8 = 8/1

Step 2: Convert the fractions to have a common denominator. The common denominator for 66 and 64 is 264 (the least common multiple of 66 and 64).

33/66 = (33 * 4)/(66 * 4) = 132/264 56/64 = (56 * 4)/(64 * 4) = 224/264

Step 3: Now, add the fractions:

-2/1 + 132/264 + 8/1 + 224/264

Step 4: Combine the whole numbers and fractions separately:

Whole numbers: -2 + 8 = 6

Fractions: 132/264 + 224/264 = 356/264

Step 5: Simplify the fraction, if possible:

356/264 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 4:

356 ÷ 4 = 89 264 ÷ 4 = 66

So, 356/264 simplifies to 89/66.

Step 6: Combine the whole number and simplified fraction:

6 89/66

Therefore, the simplified result of the expression -2 + 33/66 + 8 + 56/64 is 6 89/66.
