Answer:

[tex]2\frac{5}{12}[/tex]

Evaluate. Subtract 3 by 1

[tex]3 - 1 = 2[/tex]

Find the least common denominators of the fractions, multiply them by the least common denominators, then subtract.

[tex]\frac{2 * 4}{3 * 4} = \frac{8}{12}[/tex]

[tex]\frac{1 * 3}{4 * 3} = \frac{3}{12}[/tex]

Now subtract.

[tex]\frac{8}{12} - \frac{3}{12} = \frac{5}{12}[/tex]

Add the whole number you found earlier from subtracting 3 and 1 by the new fraction, 5/12

[tex]2 + \frac{5}{12} = 2\frac{5}{12}[/tex]
