Answer key and explanations
-
D. \(4\)
Negative divided by negative is positive. Calculate the magnitude: \(36\div9=4\). Apply sign rule: \((-)\div(-)=(+)\). Thus \(-36\div(-9)=4\).
-
A. \(-8\)
Positive divided by negative is negative: \(48\div(-6)=-8\).
-
A. \(-9\)
Negative divided by positive is negative: \(-72\div8=-9\).
-
C. \(\frac{3}{2}\)
Multiply by the reciprocal: \(\frac{3}{4}\div\frac{1}{2}=\frac{3}{4}\times\frac{2}{1}=\frac{6}{4}=\frac{3}{2}\).
-
B. \(\frac{3}{2}\)
\(\frac{5}{6}\div\frac{5}{9}=\frac{5}{6}\times\frac{9}{5}=\frac{45}{30}=\frac{3}{2}\).
-
C. \(\frac{4}{7}\div\frac{2}{7}\)
\(\frac{4}{7}\div\frac{2}{7}=\frac{4}{7}\times\frac{7}{2}=\frac{4}{2}=2\).
-
C. \(3\)
Convert: \(2\frac{1}{4}=\frac{9}{4}\). Then \(\frac{9}{4}\div\frac{3}{4}=\frac{9}{4}\times\frac{4}{3}=\frac{9}{3}=3\).
-
A. \(-\frac{5}{6}\)
\(-\frac{2}{3}\div\frac{4}{5}=-\frac{2}{3}\times\frac{5}{4}=-\frac{10}{12}=-\frac{5}{6}\).
