Solve 3*(43/5-2)-1=

$$3 \cdot ( 4 \frac { 3 } { 5 } - 2 ) - 1 =$$

Evaluate

$$\frac{34}{5}=6.8$$

Solution Steps

Multiply 4 and 5 to get 20.

$$3\left(\frac{20+3}{5}-2\right)-1$$

Add 20 and 3 to get 23.

$$3\left(\frac{23}{5}-2\right)-1$$

Convert 2 to fraction \frac{10}{5}.

$$3\left(\frac{23}{5}-\frac{10}{5}\right)-1$$

Since \frac{23}{5} and \frac{10}{5} have the same denominator, subtract them by subtracting their numerators.

$$3\times \frac{23-10}{5}-1$$

Subtract 10 from 23 to get 13.

$$3\times \frac{13}{5}-1$$

Express 3\times \frac{13}{5} as a single fraction.

$$\frac{3\times 13}{5}-1$$

Multiply 3 and 13 to get 39.

$$\frac{39}{5}-1$$

Convert 1 to fraction \frac{5}{5}.

$$\frac{39}{5}-\frac{5}{5}$$

Since \frac{39}{5} and \frac{5}{5} have the same denominator, subtract them by subtracting their numerators.

$$\frac{39-5}{5}$$

Subtract 5 from 39 to get 34.

$$\frac{34}{5}$$

Factor

$$\frac{2 \cdot 17}{5} = 6\frac{4}{5} = 6.8$$
