Solve (9/10+1/10)-4/7

$$( \frac{ 9 }{ 10 } + \frac{ 1 }{ 10 } )- \frac{ 4 }{ 7 }$$

Evaluate

$$\frac{3}{7}\approx 0.428571429$$

Solution Steps

Since \frac{9}{10} and \frac{1}{10} have the same denominator, add them by adding their numerators.

$$\frac{9+1}{10}-\frac{4}{7}$$

Add 9 and 1 to get 10.

$$\frac{10}{10}-\frac{4}{7}$$

Divide 10 by 10 to get 1.

$$1-\frac{4}{7}$$

Convert 1 to fraction \frac{7}{7}.

$$\frac{7}{7}-\frac{4}{7}$$

Since \frac{7}{7} and \frac{4}{7} have the same denominator, subtract them by subtracting their numerators.

$$\frac{7-4}{7}$$

Subtract 4 from 7 to get 3.

$$\frac{3}{7}$$

Factor

$$\frac{3}{7} = 0.42857142857142855$$
