Answer 1

1)1.2:36=1/30
2)1.2:0,25=4 4/5
3)1/30+4 4/5=1/30+4 24/30=4 25/30=4 5/6
4)4 5/6-1 5/16=4 40/48-1 15/48=3 25/48
5)3 25/48:169 20/5=169/48*5/845+20=1/960 
Но у тебя не понятно там точно 169 двадцать пятых

Answer 2

To solve this expression, we need to follow the order of operations, which is:

1. First, we need to solve any expressions inside parentheses or brackets. In this case, there is only one set of parentheses: (1,2:36+1,2:0,25-дробь 1 целая пять шестнадцытих).

2. Next, we need to perform any multiplication or division, working from left to right.

3. Finally, we need to perform any addition or subtraction, working from left to right.

Let's start by solving the expression inside the parentheses:

1,2:36 + 1,2:0,25 - дробь 1 целая пять шестнадцатых = 1.5 + 1.125 - 1.3125 = 1.3125

Now we can substitute this value back into the original expression:

(1,2:36+1,2:0,25-дробь 1 целая пять шестнадцатых) : дробь 169 двадцать пятых = 1,3125 : 169/20

To divide by a fraction, we can multiply by its reciprocal (the flipped version):

= 1,3125 * 20/169 = 0,155334

Therefore, the answer is 0,155334.
