Question 2
7 1/2 ÷ 3/4 = ?
The answer is: 7 1/2 ÷ 3/4 = 15/2 ÷ 3/4 = 15/2 x 4/3 = 60/6 = 10 packages.
7 1/2 ÷ 3/4 = ?
The answer is: 7 1/2 ÷ 3/4 = 15/2 ÷ 3/4 = 15/2 x 4/3 = 60/6 = 10 packages.
Question 3
2 3/4 + 1 1/3 ÷ 3/2 x 1/4 =
11/4 + 4/3 ÷ 3/2 x 1/4 =
11/4 + 4/3 x 2/3 x 1/4 =
11/4 + 8/36 =
99/36 + 8/36 =
107/36 or 2 35/36
2 3/4 + 1 1/3 ÷ 3/2 x 1/4 =
11/4 + 4/3 ÷ 3/2 x 1/4 =
11/4 + 4/3 x 2/3 x 1/4 =
11/4 + 8/36 =
99/36 + 8/36 =
107/36 or 2 35/36
Using the standard fraction division algorithm, the answer is: 7 1/2.
[3 ÷ 2/5 = 3 x 5/2 = 15/2 = 7 1/2]
