Solve 5-4+0.3*3/2

$$5-4+0.3 \times \frac{ 3 }{ 2 }$$

Evaluate

$$1.45$$

Solution Steps

Subtract 4 from 5 to get 1.

$$1+0.3\times \frac{3}{2}$$

Convert decimal number 0.3 to fraction \frac{3}{10}.

$$1+\frac{3}{10}\times \frac{3}{2}$$

Multiply \frac{3}{10} times \frac{3}{2} by multiplying numerator times numerator and denominator times denominator.

$$1+\frac{3\times 3}{10\times 2}$$

Do the multiplications in the fraction \frac{3\times 3}{10\times 2}.

$$1+\frac{9}{20}$$

Convert 1 to fraction \frac{20}{20}.

$$\frac{20}{20}+\frac{9}{20}$$

Since \frac{20}{20} and \frac{9}{20} have the same denominator, add them by adding their numerators.

$$\frac{20+9}{20}$$

Add 20 and 9 to get 29.

$$\frac{29}{20}$$

Factor

$$\frac{29}{5 \cdot 2 ^ {2}} = 1\frac{9}{20} = 1.45$$
