Question

(3,6/2,4)-(1,25*0,4)

Answer 1

(3.6:2,4)-(1,25*0,4)=1,5-0,5=1

Answer 2

To evaluate the expression (3,6/2,4) - (1,25 * 0,4), we'll perform the calculations step by step.

First, let's simplify the multiplication: 1,25 * 0,4 = 0,5

Now, let's subtract the result from (3,6/2,4): (3,6/2,4) - 0,5

To subtract two numbers in the form (a/b), we need to find a common denominator for the fractions. In this case, the common denominator is 2,4.

(3,6/2,4) = (3,6 * 2/2,4 * 2) = (7,2/4,8)

Now we can subtract the fractions: (7,2/4,8) - 0,5

To subtract fractions, we need to have the same denominator. Let's convert 0,5 into a fraction with a denominator of 4,8 (same as the other fraction): 0,5 = 0,5 * (4,8/4,8) = 2,4/4,8

Now we can subtract the fractions: (7,2/4,8) - (2,4/4,8) = (7,2 - 2,4) / 4,8

Performing the subtraction in the numerator: 7,2 - 2,4 = 4,8

The final result is: 4,8 / 4,8

Since the numerator and denominator are the same, the result is 1.

Therefore, (3,6/2,4) - (1,25 * 0,4) equals 1.
