296,2-2,7*6,6+6*0,15 398,6-3,8*7,7+3*0,06
Let's break down the calculations step by step for each expression.
First Expression: \( 296.2 - 2.7 \times 6.6 + 6 \times 0.15 \)
First calculate \( 2.7 \times 6.6 \): \[ 2.7 \times 6.6 = 17.82 \]
Next, calculate \( 6 \times 0.15 \): \[ 6 \times 0.15 = 0.9 \]
Now substitute these back into the expression: \[ 296.2 - 17.82 + 0.9 \]
Calculate \( 296.2 - 17.82 \): \[ 296.2 - 17.82 = 278.38 \]
Finally, add \( 0.9 \): \[ 278.38 + 0.9 = 279.28 \]
So, the result of the first expression is 279.28.
Second Expression: \( 398.6 - 3.8 \times 7.7 + 3 \times 0.06 \)
First calculate \( 3.8 \times 7.7 \): \[ 3.8 \times 7.7 = 29.26 \]
Next, calculate \( 3 \times 0.06 \): \[ 3 \times 0.06 = 0.18 \]
Now substitute these back into the expression: \[ 398.6 - 29.26 + 0.18 \]
Calculate \( 398.6 - 29.26 \): \[ 398.6 - 29.26 = 369.34 \]
Finally, add \( 0.18 \): \[ 369.34 + 0.18 = 369.52 \]
So, the result of the second expression is 369.52.
Final Results:
- First Expression: 279.28
- Second Expression: 369.52
