Solve y=21/5*31/4

$$y = 2 \frac { 1 } { 5 } \times 3 \frac { 1 } { 4 }$$

Solve for y

$$y = \frac{143}{20} = 7\frac{3}{20} = 7.15$$

Steps for Solving Linear Equation

Multiply 2 and 5 to get 10.

$$y=\frac{10+1}{5}\times \frac{3\times 4+1}{4}$$

Add 10 and 1 to get 11.

$$y=\frac{11}{5}\times \frac{3\times 4+1}{4}$$

Multiply 3 and 4 to get 12.

$$y=\frac{11}{5}\times \frac{12+1}{4}$$

Add 12 and 1 to get 13.

$$y=\frac{11}{5}\times \frac{13}{4}$$

Multiply \frac{11}{5} times \frac{13}{4} by multiplying numerator times numerator and denominator times denominator.

$$y=\frac{11\times 13}{5\times 4}$$

Do the multiplications in the fraction \frac{11\times 13}{5\times 4}.

$$y=\frac{143}{20}$$

Assign y

$$y≔\frac{143}{20}$$
