Question

x/3+ 2x/15< 2/3

Answer 1

you need a common denominator to add the fractions on the left of the inequality.

Try 15...

\[(\frac{ x }{ 3 })(\frac{ 5 }{ 5 }) + \frac{ 2x }{ 15 }< \frac{ 2 }{ 3 }\]
\[\frac{ 5x }{ 15 } + \frac{ 2x }{ 15 }< \frac{ 2 }{ 3 }\]
\[\frac{ 5x + 2x }{ 15 } < \frac{ 2 }{ 3 }\]
