Answer 2

To solve the expression 2:5:6×7:7×8+6, we need to follow the order of operations, which is usually remembered using the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). First, let's simplify any calculations inside parentheses or brackets. In this case, there are none. Next, let's handle any exponents. Again, there are none. Moving on to multiplication and division from left to right, we have: 2 : 5 : 6 × 7 : 7 × 8 + 6 First, let's calculate 2 divided by 5: 2 ÷ 5 = 0.4 (rounded to one decimal place) Now, we have: 0.4 : 6 × 7 : 7 × 8 + 6 Next, let's calculate: 0.4 : 6 = 0.0667 (rounded to four decimal places) Now, we have: 0.0667 × 7 : 7 × 8 + 6 Let's calculate 0.0667 multiplied by 7: 0.0667 × 7 = 0.4669 (rounded to four decimal places) Now, we have: 0.4669 : 7 × 8 + 6 Next, let's calculate: 0.4669 : 7 = 0.0667 (rounded to four decimal places) Now, we have: 0.0667 × 8 + 6 Let's calculate: 0.0667 × 8 = 0.5336 (rounded to four decimal places) Now, we have: 0.5336 + 6 Finally, let's calculate: 0.5336 + 6 = 6.5336 (rounded to four decimal places) Therefore, the solution to the expression 2:5:6×7:7×8+6 is approximately 6.5336.
