Solve 15-51/3*21/4

$$15-5 \frac{ 1 }{ 3 } \times 2 \frac{ 1 }{ 4 }$$

Evaluate

$$3$$

Solution Steps

Multiply 5 and 3 to get 15.

$$15-\frac{15+1}{3}\times \frac{2\times 4+1}{4}$$

Add 15 and 1 to get 16.

$$15-\frac{16}{3}\times \frac{2\times 4+1}{4}$$

Multiply 2 and 4 to get 8.

$$15-\frac{16}{3}\times \frac{8+1}{4}$$

Add 8 and 1 to get 9.

$$15-\frac{16}{3}\times \frac{9}{4}$$

Multiply \frac{16}{3} times \frac{9}{4} by multiplying numerator times numerator and denominator times denominator.

$$15-\frac{16\times 9}{3\times 4}$$

Do the multiplications in the fraction \frac{16\times 9}{3\times 4}.

$$15-\frac{144}{12}$$

Divide 144 by 12 to get 12.

$$15-12$$

Subtract 12 from 15 to get 3.

$$3$$
