Question

(9/45-0,24)*4,5-0,82

Answer 1

1)9:45=0,2
2)0,2-0,24= -0,04
3)0,04*4,5= -0,18
4)0,18-0,82= -1

Answer 2

Let's solve the expression step by step:

Step 1: Calculate the fraction (9/45 - 0.24) 9/45 can be simplified to 1/5, so the expression becomes: (1/5 - 0.24)

Step 2: Subtract 0.24 from 1/5 1/5 - 0.24 = (1/5) - (24/100) = (1/5) - (6/25) = (5/25) - (6/25) = -1/25

Step 3: Multiply the result by 4.5 (-1/25) * 4.5 = -4.5/25

Step 4: Subtract 0.82 from the previous result (-4.5/25) - 0.82

To perform the subtraction, we need a common denominator. The common denominator for 25 and 100 is 100. So, we need to convert -4.5/25 to an equivalent fraction with a denominator of 100:

(-4.5/25) * (4/4) = (-18/100)

Now, we can proceed with the subtraction:

(-18/100) - 0.82 = (-18/100) - (82/100) = (-18 - 82)/100 = -100/100 = -1

The final result is -1.
