Solve =1-2*15/28+3/28/3*1

$$= 1 - \frac { 2 \cdot \frac { 15 } { 28 } + \frac { 3 } { 28 } } { 3 } \cdot 1$$

Evaluate

$$\frac{17}{28}\approx 0.607142857$$

Solution Steps

Express 2\times \frac{15}{28} as a single fraction.

$$1-\frac{\frac{2\times 15}{28}+\frac{3}{28}}{3}\times 1$$

Multiply 2 and 15 to get 30.

$$1-\frac{\frac{30}{28}+\frac{3}{28}}{3}\times 1$$

Since \frac{30}{28} and \frac{3}{28} have the same denominator, add them by adding their numerators.

$$1-\frac{\frac{30+3}{28}}{3}\times 1$$

Add 30 and 3 to get 33.

$$1-\frac{\frac{33}{28}}{3}\times 1$$

Express \frac{\frac{33}{28}}{3} as a single fraction.

$$1-\frac{33}{28\times 3}\times 1$$

Multiply 28 and 3 to get 84.

$$1-\frac{33}{84}\times 1$$

Reduce the fraction \frac{33}{84} to lowest terms by extracting and canceling out 3.

$$1-\frac{11}{28}\times 1$$

Multiply \frac{11}{28} and 1 to get \frac{11}{28}.

$$1-\frac{11}{28}$$

Convert 1 to fraction \frac{28}{28}.

$$\frac{28}{28}-\frac{11}{28}$$

Since \frac{28}{28} and \frac{11}{28} have the same denominator, subtract them by subtracting their numerators.

$$\frac{28-11}{28}$$

Subtract 11 from 28 to get 17.

$$\frac{17}{28}$$

Factor

$$\frac{17}{2 ^ {2} \cdot 7} = 0.6071428571428571$$
