<h3>Fractions and proportions</h3>
Fractions are written as a ratio of two integers. For instance a/b is a fraction.
Let the time it will take them to complete the job together be "x" such that;
1/x = 1/5 + 1/7
Simplify
1/x = 7+5/35
1/x = 12/35
Cross multiply
12x = 35
x = 35/12
x = 2 11/12 hours
Therefore it will take both of them 2 11/12 hours to complete the room
