Solution Steps

Add 1.5 and 2.8 to get 4.3.

$$4.3+\frac{3.6}{3}$$

Expand \frac{3.6}{3} by multiplying both numerator and the denominator by 10.

$$4.3+\frac{36}{30}$$

Reduce the fraction \frac{36}{30} to lowest terms by extracting and canceling out 6.

$$4.3+\frac{6}{5}$$

Convert decimal number 4.3 to fraction \frac{43}{10}.

$$\frac{43}{10}+\frac{6}{5}$$

Least common multiple of 10 and 5 is 10. Convert \frac{43}{10} and \frac{6}{5} to fractions with denominator 10.

$$\frac{43}{10}+\frac{12}{10}$$

Since \frac{43}{10} and \frac{12}{10} have the same denominator, add them by adding their numerators.

$$\frac{43+12}{10}$$

Add 43 and 12 to get 55.

$$\frac{55}{10}$$

Reduce the fraction \frac{55}{10} to lowest terms by extracting and canceling out 5.

$$\frac{11}{2}$$

Factor

$$\frac{11}{2} = 5\frac{1}{2} = 5.5$$
