Most Upvoted Answer
(-3/4*8/15) -(2/5*-3/8) +(7/8*(-16/35)?
Solution:
Step 1: Calculate (-3/4 * 8/15)
- To multiply fractions, multiply the numerators together and the denominators together.
- (-3/4 * 8/15) = (-3 * 8) / (4 * 15) = -24 / 60 = -2 / 5
Step 2: Calculate (2/5 * -3/8)
- (-2/5 * -3/8) = (2 * -3) / (5 * 8) = -6 / 40 = -3 / 20
Step 3: Calculate (7/8 * -16/35)
- (7/8 * -16/35) = (7 * -16) / (8 * 35) = -112 / 280 = -4 / 10 = -2 / 5
Step 4: Combine the results
- (-2/5) - (-3/20) + (-2/5) = -2/5 + 3/20 - 2/5
- Find a common denominator, which is 20.
- -16/20 + 3/20 - 8/20 = -21/20
Final Answer:
- The final result after simplifying is -21/20.
