A) (3/7 + 5/12) 4 First, find a common denominator for 7 and 12, which is 84. Now convert the fractions: 3/7 = 36/84 5/12 = 35/84 Adding them together: (36/84 + 35/84) = 71/84 Now multiply by 4: 71/84 4 = 284/84 = 71/21
Therefore, the value of the expression is 71/21.
B) (5/6 - 2/9) / 11 First, find a common denominator for 6 and 9, which is 18. Now convert the fractions: 5/6 = 15/18 2/9 = 4/18 Subtracting them: (15/18 - 4/18) = 11/18 Now divide by 11: 11/18 / 11 = 1/18
A) (3/7 + 5/12) 4
First, find a common denominator for 7 and 12, which is 84.
Now convert the fractions:
3/7 = 36/84
5/12 = 35/84
Adding them together:
(36/84 + 35/84) = 71/84
Now multiply by 4:
71/84 4 = 284/84 = 71/21
Therefore, the value of the expression is 71/21.
B) (5/6 - 2/9) / 11
First, find a common denominator for 6 and 9, which is 18.
Now convert the fractions:
5/6 = 15/18
2/9 = 4/18
Subtracting them:
(15/18 - 4/18) = 11/18
Now divide by 11:
11/18 / 11 = 1/18
Therefore, the value of the expression is 1/18.
