2. Hello, Chris!

Solve the following proportion for the unkown quantities:

. . $a : 58 : 132 \:= \:38 : 27 : b$
Take them in pairs . . .

. . $a:58 \:=\:38:27\quad\Rightarrow\quad\frac{a}{58} \:=\:\frac{38}{27}\quad\Rightarrow\quad a \:=\:\frac{2204}{27}$

. . $58:132 \:=\:27:b\quad\Rightarrow\quad \frac{58}{132}\:=\:\frac{27}{b}\quad\Rightarrow\qu ad b \:=\:\frac{1782}{29}$
