To solve this problem, we need to first simplify the expression inside the parentheses, then divide the result by 0.8.
First, let's work out the expression inside the parentheses:(3 2/3 + 1 3/4) : (67/12 - 21/4)Convert the mixed numbers to improper fractions:(11/3 + 7/4) : (67/12 - 21/4)Find a common denominator:(44/12 + 21/12) : (67/12 - 63/12)Combine the fractions:65/12 : 4/12Divide the fractions:65/12 ÷ 4/12 = 65/12 * 12/4 = 65/4 = 16.25
Now, divide the result by 0.8:16.25 / 0.8 = 20.3125
Therefore, the final answer is 20.3125.
To solve this problem, we need to first simplify the expression inside the parentheses, then divide the result by 0.8.
First, let's work out the expression inside the parentheses:
(3 2/3 + 1 3/4) : (67/12 - 21/4)
Convert the mixed numbers to improper fractions:
(11/3 + 7/4) : (67/12 - 21/4)
Find a common denominator:
(44/12 + 21/12) : (67/12 - 63/12)
Combine the fractions:
65/12 : 4/12
Divide the fractions:
65/12 ÷ 4/12 = 65/12 * 12/4 = 65/4 = 16.25
Now, divide the result by 0.8:
16.25 / 0.8 = 20.3125
Therefore, the final answer is 20.3125.
