Solve (3.(80-8.9)+6):(7.6-2-5.7)+36:4.5

$$( 3 . ( 80 - 8.9 ) + 6 ) : ( 7.6 - 2 - 5.7 ) + 36 : 4.5$$

Evaluate

$$-2185$$

Solution Steps

Subtract 8.9 from 80 to get 71.1.

$$\frac{3\times 71.1+6}{7.6-2-5.7}+\frac{36}{4.5}$$

Multiply 3 and 71.1 to get 213.3.

$$\frac{213.3+6}{7.6-2-5.7}+\frac{36}{4.5}$$

Add 213.3 and 6 to get 219.3.

$$\frac{219.3}{7.6-2-5.7}+\frac{36}{4.5}$$

Subtract 2 from 7.6 to get 5.6.

$$\frac{219.3}{5.6-5.7}+\frac{36}{4.5}$$

Subtract 5.7 from 5.6 to get -0.1.

$$\frac{219.3}{-0.1}+\frac{36}{4.5}$$

Expand \frac{219.3}{-0.1} by multiplying both numerator and the denominator by 10.

$$\frac{2193}{-1}+\frac{36}{4.5}$$

Fraction \frac{2193}{-1} can be rewritten as -2193 by extracting the negative sign.

$$-2193+\frac{36}{4.5}$$

Expand \frac{36}{4.5} by multiplying both numerator and the denominator by 10.

$$-2193+\frac{360}{45}$$

Divide 360 by 45 to get 8.

$$-2193+8$$

Add -2193 and 8 to get -2185.

$$-2185$$

Factor
