Question

204*0,7/1 1/6*0,51+3 1/3-0,2/0,3-2 1/2

Answer 1

1) 204•0.7:11:6•0.51+3= 4.1034545454
2) 1:3-0.2:0.3-21:2= -10.8333333334

Answer 2

Let's break down the expression step by step:

1. 204 * 0.7 / 1: Multiply 204 by 0.7, then divide the result by 1. 204 * 0.7 = 142.8 142.8 / 1 = 142.8

2. 1/6 * 0.51 + 3 1/3: Divide 1 by 6, then multiply the result by 0.51. 1 / 6 = 0.166666... 0.166666... * 0.51 = 0.085

   Next, convert 3 1/3 to an improper fraction: 3 1/3 = 3 + 1/3 = 3 + 0.333333... = 3.333333...

   Now, add the two results: 0.085 + 3.333333... = 3.418

3. 0.2 / 0.3: Divide 0.2 by 0.3. 0.2 / 0.3 = 0.666666...

4. Subtract 2 1/2 from the result obtained in step 3: Convert 2 1/2 to an improper fraction: 2 1/2 = 2 + 1/2 = 2 + 0.5 = 2.5

   Now, subtract 2.5 from 0.666666...: 0.666666... - 2.5 = -1.833333...

Putting it all together, the final result is:

142.8 + 3.418 - 1.833333... ≈ 144.384
