Practice problem
Which of the following are fraction decompositions of a+b+cd\frac{a+b+c}{d}da+b+c?
ad+a+b+cd\frac{a}{d}+\frac{a+b+c}{d}da+da+b+c
ad+bd+cd\frac{a}{d}+\frac{b}{d}+\frac{c}{d}da+db+dc
bd+a+cd\frac{b}{d}+\frac{a+c}{d}db+da+c
cd+b+cd\frac{c}{d}+\frac{b+c}{d}dc+db+c
Type a concept, like “slope” or “photosynthesis”.
