Solve 153/4+121/4

$$15 \frac { 3 } { 4 } + 12 \frac { 1 } { 4 }$$

Evaluate

$$28$$

Solution Steps

Multiply 15 and 4 to get 60.

$$\frac{60+3}{4}+\frac{12\times 4+1}{4}$$

Add 60 and 3 to get 63.

$$\frac{63}{4}+\frac{12\times 4+1}{4}$$

Multiply 12 and 4 to get 48.

$$\frac{63}{4}+\frac{48+1}{4}$$

Add 48 and 1 to get 49.

$$\frac{63}{4}+\frac{49}{4}$$

Since \frac{63}{4} and \frac{49}{4} have the same denominator, add them by adding their numerators.

$$\frac{63+49}{4}$$

Add 63 and 49 to get 112.

$$\frac{112}{4}$$

Divide 112 by 4 to get 28.

$$28$$

Factor

$$2^{2}\times 7$$
