Question

Ina fish tank, 8/11 of the fish have red stripes on them.If 16 of the fish have red stripes how many fish are in the tank

Answer 1

a whole is 1, thus in 11th terms, that'd be 11/11 namely eleven elevenths, is a whole.

we know that 8/11 of that whole is really 16 fishes, if the whole is "x", what is "x"?

`\bf \begin{array}{ccll} fraction&total\\ \cline{1-2}\\ (8)/(11)&16\\\\ (11)/(11)&x \end{array}\implies \cfrac{~~(8)/(11)~~}{(11)/(11)}=\cfrac{16}{x}\implies \cfrac{~~(8)/(11)~~}{1}=\cfrac{16}{x} \\\\\\ \cfrac{8}{11}=\cfrac{16}{x}\implies 8x=176\implies x=\cfrac{176}{8}\implies x=22`
