Question

6 1/4 * 8 - 3 2/3 * 5 1/2 + 2 2/5 * 4 7/12 =

Answer 1

6 1/4 * 8=50
3 2/3 * 5 1/2= 11/3 * 11/2= 121/5=24 1/5
2 2/5 * 4 7/12= 12/5 * 55/12= 1/1 * 11/1=11
50- 24 1/5= 25 4/5
25 4/5+11=36 4/5

Answer 2

To solve this expression, we'll follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

Let's calculate it step by step:

1. First, deal with the multiplication: 6 1/4 * 8 = (6 + 1/4) * 8 = (25/4) * 8 = 25 * 2 = 50 3 2/3 * 5 1/2 = (3 + 2/3) * (5 + 1/2) = (11/3) * (11/2) = 121/6

2. Now, perform the multiplication with the fractions: 121/6 * 2 2/5 = (121/6) * (2 + 2/5) = (121/6) * (12/5) = 121/6 * 12/5 = 121 * 2 = 242

3. Finally, perform the addition and subtraction: 50 - 242 + 2 2/5 * 4 7/12 = 50 - 242 + (2 + 2/5) * (4 + 7/12) = 50 - 242 + (12/5) * (55/12) 50 - 242 + 660/60 = 50 - 242 + 11 = -192

So, the final result of the expression is -192.
