Question

0.8(3)-0.4(6) _________ : 1/125= 1+5\6

Answer 1

Ответ: 0.............

Answer 2

Let's solve the expression step by step:

Step 1: Calculate the values inside the parentheses: 0.8(3) = 0.8 * 3 = 2.4 0.4(6) = 0.4 * 6 = 2.4

Step 2: Substitute the calculated values back into the expression: 0.8(3) - 0.4(6) = 2.4 - 2.4 = 0

Now let's solve the equation: 1/125 = 1 + 5/6

Step 3: Convert the mixed number to an improper fraction: 1 + 5/6 = 6/6 + 5/6 = 11/6

Step 4: Now we have the equation: 1/125 = 11/6

To solve this equation for the unknown, you can cross-multiply:

1 * 6 = 125 * 11 6 = 1375

However, 6 is not equal to 1375, which means there is no valid solution to the equation.

Therefore, the expression 0.8(3) - 0.4(6) equals 0, but the equation 1/125 = 1 + 5/6 has no valid solution.
