- 3/7+(- 6 5/8)+4/9+(-4/7)+(-3/8)+ 5/9 плизззз

Answer 1

-3/7-53/8+4/9-4/7-3/8-3/8+5/9=-7

Answer 2

Sure, let's simplify the given expression step by step:

1. 3/7 + (-6 5/8) + 4/9 + (-4/7) + (-3/8) + 5/9

First, we need to convert the mixed number (-6 5/8) into an improper fraction: -6 5/8 = -(6 + 5/8) = -((6 * 8 + 5) / 8) = -(53/8)

Now, the expression becomes: 3/7 + (-53/8) + 4/9 + (-4/7) + (-3/8) + 5/9

2. Find a common denominator for all the fractions. The least common multiple of 7, 8, and 9 is 504. Let's rewrite the fractions with the common denominator:

(3/7) * (72/72) + (-53/8) * (63/63) + (4/9) * (56/56) + (-4/7) * (72/72) + (-3/8) * (63/63) + (5/9) * (56/56)

3. Now, add the fractions together:

(216/504) + (-3336/504) + (224/504) + (-288/504) + (-189/504) + (280/504)

4. Combine the fractions:

(216 - 3336 + 224 - 288 - 189 + 280) / 504

5. Perform the arithmetic operations:

(-2893) / 504

6. Simplify the fraction if possible. In this case, it's already in its simplest form.

The final result is: -2893/504 or approximately -5.7381
