Question

4/25:(12/25-4/15)+15/18+4/15= (ПО ДЕЙСТВИЯМ!)

Answer 1

4/25:(12/25-4/15)+15/18+4/15=1 51/60
12/25-4/15=16/75
4/25:16/75=3/4
3/4+15/18=57/36
57/36+4/15=666/360=111/60=1 51/60

Answer 2

To perform the calculations indicated, let's break down the expression step by step:

First, let's simplify the expression within the parentheses:

12/25 - 4/15 = (180/375) - (100/150) = 180/375 - 250/375 = (180 - 250)/375 = -70/375

Now, let's add the fractions:

(-70/375) + 15/18 + 4/15 = (-70/375) + (125/150) + (100/150) = (-70 + 125 + 100)/375 = 155/375

The final result is 155/375.
