Question

161-(469,7:15,4+9,52)*1,5

Answer 1

161-(469,7:15,4+9,52)*1,5= 100,97
1) 469,7:15,4= 30,5
2) 30,5+9,52=40,02
3)40,02*1,5=60,03
4) 161-60,03=100,97

Answer 2

To simplify the expression, we need to perform the operations within the parentheses first, and then evaluate the expression from left to right according to the order of operations (PEMDAS).

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

4 + 9 = 13

9,52 rounded to the nearest whole number is 10

469,7:15 = 31,31333333333333 (rounded to 14 decimal places)

31,31333333333333 * 10 = 313,1333333333333 (rounded to 14 decimal places)

So, the expression within the parentheses evaluates to 313,1333333333333.

Now, we can substitute this value back into the original expression and simplify further:

161 - (313,1333333333333 * 1.5)

= 161 - 469,69999999999993

= -308,53999999999996

Therefore, the simplified expression is -308.54 (rounded to two decimal places).
