Multiply 1 and 4 to get 4.

$$\frac{4+3}{4}\times \frac{2\times 3+1}{3}$$

Add 4 and 3 to get 7.

$$\frac{7}{4}\times \frac{2\times 3+1}{3}$$

Multiply 2 and 3 to get 6.

$$\frac{7}{4}\times \frac{6+1}{3}$$

Add 6 and 1 to get 7.

$$\frac{7}{4}\times \frac{7}{3}$$

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