<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

Answer:
75,071,003,569
Step-by-step explanation:
use pemdas
means we must multiply before adding and subtracting
6,532 + 76,544 × 980,766 + 9,888 - 765,655
6,632 + 75,071,752,704 + 9,888 - 765,655
now we add and subtract, starting from left to right
75,071,759336 + 9,888 - 765,655
75,071,769,224 - 765,655
75,071,003,569
