Solve (8,2-1,4+2,2):0,3-(1,4+0,9*0,1)

$$( 8,2 - 1,4 + 2,2 ) : 0,3 - ( 1,4 + 0,9 \cdot 0,1 )$$

Evaluate

$$28,51$$

Solution Steps

Subtract 1,4 from 8,2 to get 6,8.

$$\frac{6,8+2,2}{0,3}-\left(1,4+0,9\times 0,1\right)$$

Add 6,8 and 2,2 to get 9.

$$\frac{9}{0,3}-\left(1,4+0,9\times 0,1\right)$$

Expand \frac{9}{0,3} by multiplying both numerator and the denominator by 10.

$$\frac{90}{3}-\left(1,4+0,9\times 0,1\right)$$

Divide 90 by 3 to get 30.

$$30-\left(1,4+0,9\times 0,1\right)$$

Multiply 0,9 and 0,1 to get 0,09.

$$30-\left(1,4+0,09\right)$$

Add 1,4 and 0,09 to get 1,49.

$$30-1,49$$

Subtract 1,49 from 30 to get 28,51.

$$28,51$$

Factor

$$\frac{2851}{2 ^ {2} \cdot 5 ^ {2}} = 28\frac{51}{100} = 28.51$$
