Solve 3,5+41/2-7/2=

$$3,5 + 4 \frac { 1 } { 2 } - \frac { 7 } { 2 } =$$

Evaluate

$$4,5$$

Solution Steps

Multiply 4 and 2 to get 8.

$$3,5+\frac{8+1}{2}-\frac{7}{2}$$

Add 8 and 1 to get 9.

$$3,5+\frac{9}{2}-\frac{7}{2}$$

Convert decimal number 3,5 to fraction \frac{35}{10}. Reduce the fraction \frac{35}{10} to lowest terms by extracting and canceling out 5.

$$\frac{7}{2}+\frac{9}{2}-\frac{7}{2}$$

Since \frac{7}{2} and \frac{9}{2} have the same denominator, add them by adding their numerators.

$$\frac{7+9}{2}-\frac{7}{2}$$

Add 7 and 9 to get 16.

$$\frac{16}{2}-\frac{7}{2}$$

Since \frac{16}{2} and \frac{7}{2} have the same denominator, subtract them by subtracting their numerators.

$$\frac{16-7}{2}$$

Subtract 7 from 16 to get 9.

$$\frac{9}{2}$$

Factor

$$\frac{3 ^ {2}}{2} = 4\frac{1}{2} = 4.5$$
