Most Upvoted Answer
(6/11×4/7)-(9/12×4/3) (7/8×64/21)?
Solution:
Simplifying the given expression:
Step 1: Simplify fractions within the brackets first.
- 6/11 x 4/7 = 24/77
- 9/12 x 4/3 = 3/4 x 4/3 = 1
Therefore, the expression becomes:
- 24/77 - 1 x (7/8 x 64/21)
Step 2: Simplify the multiplication inside the brackets.
- 7/8 x 64/21 = 448/168 = 56/21 = 8/3
Therefore, the expression becomes:
- 24/77 - 1 x 8/3
Step 3: Simplify the multiplication.
- 1 x 8/3 = 8/3
Therefore, the expression becomes:
- 24/77 - 8/3
Converting the fractions into like fractions:
Step 1: Find the LCM of 77 and 3, which is 231.
Step 2: Convert the fractions into like fractions with the denominator 231.
- 24/77 x 3/3 = 72/231
- 8/3 x 77/77 = 616/231
Therefore, the expression becomes:
- 72/231 - 616/231
Subtracting the fractions:
- 72/231 - 616/231 = -544/231
Therefore, the final answer is -544/231.
Answer: -544/231.
