Solve 6*4-64:(-3,3+1,9)=

$$6 \cdot 4 - 64 : ( - 3,3 + 1,9 ) =$$

Evaluate

$$\frac{488}{7}\approx 69,714285714$$

Solution Steps

Multiply 6 and 4 to get 24.

$$24-\frac{64}{-3,3+1,9}$$

Add -3,3 and 1,9 to get -1,4.

$$24-\frac{64}{-1,4}$$

Expand \frac{64}{-1,4} by multiplying both numerator and the denominator by 10.

$$24-\frac{640}{-14}$$

Reduce the fraction \frac{640}{-14} to lowest terms by extracting and canceling out 2.

$$24-\left(-\frac{320}{7}\right)$$

The opposite of -\frac{320}{7} is \frac{320}{7}.

$$24+\frac{320}{7}$$

Convert 24 to fraction \frac{168}{7}.

$$\frac{168}{7}+\frac{320}{7}$$

Since \frac{168}{7} and \frac{320}{7} have the same denominator, add them by adding their numerators.

$$\frac{168+320}{7}$$

Add 168 and 320 to get 488.

$$\frac{488}{7}$$

Factor

$$\frac{61 \cdot 2 ^ {3}}{7} = 69\frac{5}{7} = 69.71428571428571$$
