Solve 51/4*31/2=

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

Evaluate

$$\frac{147}{8}=18.375$$

Solution Steps

Multiply 5 and 4 to get 20.

$$\frac{20+1}{4}\times \frac{3\times 2+1}{2}$$

Add 20 and 1 to get 21.

$$\frac{21}{4}\times \frac{3\times 2+1}{2}$$

Multiply 3 and 2 to get 6.

$$\frac{21}{4}\times \frac{6+1}{2}$$

Add 6 and 1 to get 7.

$$\frac{21}{4}\times \frac{7}{2}$$

Multiply \frac{21}{4} times \frac{7}{2} by multiplying numerator times numerator and denominator times denominator.

$$\frac{21\times 7}{4\times 2}$$
