Solve A=(15/4-5/2)*7/5

$$A = ( \frac { 15 } { 4 } - \frac { 5 } { 2 } ) \times \frac { 7 } { 5 }$$

Solve for A

$$A = \frac{7}{4} = 1\frac{3}{4} = 1.75$$

Steps for Solving Linear Equation

Least common multiple of 4 and 2 is 4. Convert \frac{15}{4} and \frac{5}{2} to fractions with denominator 4.

$$A=\left(\frac{15}{4}-\frac{10}{4}\right)\times \frac{7}{5}$$

Since \frac{15}{4} and \frac{10}{4} have the same denominator, subtract them by subtracting their numerators.

$$A=\frac{15-10}{4}\times \frac{7}{5}$$

Subtract 10 from 15 to get 5.

$$A=\frac{5}{4}\times \frac{7}{5}$$

Multiply \frac{5}{4} times \frac{7}{5} by multiplying numerator times numerator and denominator times denominator.

$$A=\frac{5\times 7}{4\times 5}$$

Cancel out 5 in both numerator and denominator.

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

Assign A

$$A≔\frac{7}{4}$$
