Reduce the fraction to lowest terms. Do not use spaces in your answer. y+5 / 2y + 10
Tcecarenko [31]

Assuming 5/2y is the fraction,

= y + 5/2y + 10

You can divide the entire fraction (both numerator and denominator) by 2

= y + 2.5/y + 10

That is as far simplified, or 'lowest terms' as it gets.
