Question

А 0,51+0,8×(5:4+38:1,9+91,2:15,2=?

Answer 1

5:4=1.25
38:1.9=20
91.2:15,2=6
1.25+20=21.25
21.25+6=27.25
0.8*27.25=21.8
0.51+21.8=22.31

Answer 2

Let's solve the expression step by step:

1. Calculate the expressions inside the parentheses first: 5 : 4 = 1.25 38 : 1.9 = 20 91.2 : 15.2 = 6

2. Add the results inside the parentheses: 1.25 + 20 + 6 = 27.25

3. Multiply 0.8 by the sum from step 2: 0.8 * 27.25 = 21.8

4. Finally, add 0.51 to the result from step 3: 0.51 + 21.8 = 22.31

So, the final result of the expression is 22.31.
