Пошаговое объяснение:

230/400-120/400-18/400=

(230-120-18)/400=92/400=

23/100 или 0,23

Так как знаменатель у дробей одинаковый,действие делаем только в числителе.Затем полученную дробь сократили на 4.

Answer 2

To calculate the expression (230/400) - (120/400) - (18/400), we'll perform the operations in the following order:

First, let's simplify the individual fractions:

230/400 = 23/40 120/400 = 3/10 18/400 = 9/200

Now, we can subtract the fractions:

(23/40) - (3/10) - (9/200)

To perform the subtraction, we need to find a common denominator for the fractions. The least common multiple (LCM) of 40, 10, and 200 is 200. Therefore, we'll convert all the fractions to have a denominator of 200:

(23/40) * (5/5) = 115/200 (3/10) * (20/20) = 60/200 (9/200)

Now we can subtract the fractions:

(115/200) - (60/200) - (9/200) = (115 - 60 - 9)/200 = 46/200

The result of the expression is 46/200, which can be simplified further if necessary.
