(−3/5)×(5 1/6)×(7 1/2)÷(−3 1/6)×(−5/7)

1 answer

To solve this expression, we can follow the order of operations, which is parentheses, multiplication/division (from left to right), and then addition/subtraction (from left to right).

Starting with the parentheses, we have:
(-3/5) × (5 1/6) × (7 1/2) ÷ (-3 1/6) × (-5/7)

Next, let's convert the mixed numbers into improper fractions:
(-3/5) × (31/6) × (15/2) ÷ (-19/6) × (-5/7)

Now, multiplying the fractions together:
((-3) × 31 × 15 × (-5)) / ((5) × (6) × (2) × (-19)) × (7)

Simplifying the numerator and denominator separately:
(-1395) / (-1140) × 7

Canceling out the negative signs:
(1395) / (1140) × 7

Simplifying the fraction:
(465/380) × (7)

Multiplying the fractions:
(465 × 7) / 380

Simplifying the fraction:
(3255) / 380

So, the simplified expression is 3255/380.
