Notice that 4:8 is the same as 1:2. So -3*2=-6. So B=-6

\[\frac{-3}{B}=\frac{4}{8}\]time and flip\[-3 \times 8 =4 \times D\]\[-24=4D\]\[D=\frac{-24}{4}\]\[D=6\]

: is mean division set eqution by fraction thane filp and time

OpenStudy (anonymous):

\[\frac{-44}{C}=\frac{12}{3}\]flip and time\[-44\times 3 = 12C\]\[-132=12C\] \[C=\frac{-132}{12}\]\[C=-11\]

now find e move 9 to another side ( 9 right now it time when move u change division,if division u change time,if add u change subtrac,if subtrac u change add)
