Question

What is greater 1/3 or 5/6

Answer 1

5/6 is greater than 1/3.

Answer 2

A simple way to turn both fractions with the same denominator is

multiply the right-side fraction by the denominator on the left-side
and
multiply the left-side fraction by the denominator of the right-side

so, let's do that then

$\bf \cfrac{1}{3}\cdot \cfrac{6}{6}\implies \cfrac{6}{18} \\\\\\ \cfrac{5}{6}\cdot \cfrac{3}{3}\implies \cfrac{15}{18}\\\\ -------------------------------\\\\ \textit{now, which one do you think is greater }\cfrac{6}{18}\ or\ \cfrac{15}{18}\qquad ?$
