Solve A=1/3-1/3*4/7

$$A = \frac { 1 } { 3 } - \frac { 1 } { 3 } \times \frac { 4 } { 7 }$$

Solve for A

$$A=\frac{1}{7}\approx 0.142857143$$

Steps for Solving Linear Equation

Multiply \frac{1}{3} times \frac{4}{7} by multiplying numerator times numerator and denominator times denominator.

$$A=\frac{1}{3}-\frac{1\times 4}{3\times 7}$$

Do the multiplications in the fraction \frac{1\times 4}{3\times 7}.

$$A=\frac{1}{3}-\frac{4}{21}$$

Least common multiple of 3 and 21 is 21. Convert \frac{1}{3} and \frac{4}{21} to fractions with denominator 21.

$$A=\frac{7}{21}-\frac{4}{21}$$

Since \frac{7}{21} and \frac{4}{21} have the same denominator, subtract them by subtracting their numerators.

$$A=\frac{7-4}{21}$$

Subtract 4 from 7 to get 3.

$$A=\frac{3}{21}$$

Reduce the fraction \frac{3}{21} to lowest terms by extracting and canceling out 3.

$$A=\frac{1}{7}$$

Assign A

$$A≔\frac{1}{7}$$
