I) 2 5 × (− 3 7 ) − 1 6 × 3 2 1 14 × 2 5?
Most Upvoted Answer
I) 2 5 × (− 3 7 ) − 1 6 × 3 2 1 14 × 2 5?
Answer
Simplifying the given expressions
- Multiplying 2 and 5 gives 10.
- Multiplying -3 and 7 gives -21.
- Multiplying -1 and 6 gives -6.
- Multiplying 3 and 2 gives 6.
- Multiplying 1 and 14 gives 14.
- Multiplying 2 and 5 gives 10.
Calculating the final answer
- 2 * 5 × (− 3 / 7 ) = -6 (Dividing -21 by 7 gives -3, then multiplying -3 with 2 and 5 gives -30, which when simplified gives -6)
- 1 / 6 × 3 / 2 = 1 / 4 (Multiplying 1 and 3 gives 3, and multiplying 6 and 2 gives 12, then dividing 3 by 12 gives 1/4)
- 1 / 14 × 2 / 5 = 1 / 35 (Multiplying 1 and 2 gives 2, and multiplying 14 and 5 gives 70, then dividing 2 by 70 gives 1/35)
- Final answer: -6 - (1/4) + (1/35) = -25/28 (Subtracting 1/4 and 1/35 from -6 gives -25/28)
Explanation
The given expression involves multiplication and division of fractions and integers. We need to simplify each term of the expression and then perform the required operations to get the final answer. To simplify the fractions, we need to find their lowest common denominator, which is the product of their denominators. We then convert the fractions to have this common denominator and then perform the required operations. Finally, we simplify the resulting fraction to get the answer in the lowest terms.
