Question

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

Answer 1

$5 \times \frac{3}{8} \times 8 \times \frac{5}{6} - 4 \times \frac{2}{5} \times 1 \times \frac{1}{6} + 6 \times \frac{5}{8} \times 8 \times \frac{5}{6} - 7 \times \frac{3}{5} \times 1 \times \frac{1}{6} = \frac{25}{2} - \frac{4}{15} + 25 - \frac{7}{10} = \frac{375 - 8 - 21}{30} + 25 = \frac{346}{30} + 25 = 11 \frac{8}{15} + 25 = 36 \frac{8}{15}$

Answer 3

To simplify the expression, follow the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets (if any)
2. Exponents/Orders (if any)
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Let's solve the expression step-by-step:

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

2. Multiply and divide from left to right:

   (5 * 3) / 8 * 8 * 5 / 6 - (4 * 2) / 5 * 1 * 1 / 6 + (6 * 5) / 8 * 8 * 5 / 6 - (7 * 3) / 5 * 1 * 1 / 6

   15 / 8 * 8 * 5 / 6 - 8 / 5 * 1 * 1 / 6 + 30 / 8 * 8 * 5 / 6 - 21 / 5 * 1 * 1 / 6

3. Continue with multiplication and division:

   (15 / 8) * 8 * 5 / 6 - (8 / 5) * 1 * 1 / 6 + (30 / 8) * 8 * 5 / 6 - (21 / 5) * 1 * 1 / 6

   15 * 5 / 6 - 8 / 5 * 1 * 1 / 6 + 30 * 5 / 6 - 21 / 5 * 1 * 1 / 6

4. Complete the remaining calculations:

   (15 * 5) / 6 - (8 / 5) * (1 * 1) / 6 + (30 * 5) / 6 - (21 / 5) * (1 * 1) / 6

   75 / 6 - (8 / 5) * 1 / 6 + 150 / 6 - 21 / 5 * 1 / 6

   12.5 - (8 / 5) * 1 / 6 + 25 - 21 / 5 * 1 / 6

5. Continue with multiplication and division:

   12.5 - (8 / 5) * (1 / 6) + 25 - (21 / 5) * (1 / 6)

   12.5 - (8 / 30) + 25 - (21 / 30)

   12.5 - 0.26666667 + 25 - 0.7

6. Perform addition and subtraction:

   12.23333333 + 25 - 0.7

   37.23333333 - 0.7

7. Final result:

   36.53333333

So, the simplified value of the expression is approximately 36.53333333.
