Answer

-6.2

Work Step by Step

First, add together the numbers in the numerator: $\frac{0.23 + 1.63}{-0.3}$ = $\frac{1.86}{-0.3}$ Now, to make division easier, multiply the numerator and denominator by 10 to get rid of the decimal: $\frac{1.86 \times 10}{-0.3 \times 10}$ = $\frac{18.6}{3}$ As the division sign means divide, this expression then becomes: 18.6 $\div$ 3 Using long division, complete this division problem. See attached image to see the long division process. 18.6 $\div$ 3 = 6.2 As the divisor of the original problem (-0.3) was negative, our answer must be negative. The answer is -6.2
