What is<br> -1 5/6 - (-3 1/4) ?

lions [1.4K]

Answer:

$1\frac{5}{12}$

Step-by-step explanation:

Eliminating a negative and changing our operation

$1\frac{5}{6} +3\frac{1}{4}$

Rewriting our equation with parts separated

$-1-\frac{5}{6} +3+\frac{1}{4}$

Solving the whole number parts

$-1+3=2$

Solving the fraction parts

$-\frac{5}{6} +\frac{1}{4} =[?]$

Find the LCD of 5/6 and 1/4 and rewrite to solve with the equivalent fractions.

LCD = 12

$-\frac{10}{12} +\frac{3}{12}=-\frac{7}{12}$

Combining the whole and fraction parts

$2-\frac{7}{12} =1\frac{5}{12}$
