Question

-1/12 - 3/4 =
A. -1/3
B. -5/6
C. 2/3

Answer 1

b

Answer 2

we have
\[-\frac{1}{12}-\frac{3}{4}\]
multiply numerator and denominator of second term by 3
\[-\frac{1}{12}-\frac{3\times 3}{4\times 3}\]
we get
\[-\frac{1}{12}-\frac{9}{12}\]
now subtract the two terms
we get
\[-\frac{10}{12}\]
DIVIDE BOTH NUMERATOR AND DENOMINATOR BY 2
WE GET
\[-\frac{5}{6}\]
