Question 31113: Hello,
It's me again, Kristin. Can you help me again with another problem?
8 1/4-5 2/3=
Now I know that you have to turn it to a whole fraction.
8*4+1=33 =33/4
5*3+2=17 =17/3 ..Now comes the LCD=12
The denominators must be divided by 12 and multiplied by the numerator
3(33)/12-(4)17/12
=99/12-68/12
=31/12
=2 7/12
Is this right?

Answer by checkley71(316)
12 1/2*10 1/3 = 25/2*31/3 OR 775/6 SQ FEET
5/12*5/12=25/144 SQ FEET
(775/6)/(25/144) OR 111600/150 OR 744 TILES ARE NEEDED
THE REAL WORLD REQUIRES A TILEMAN/WOMAN TO KNOW HOW MANY TILES HE/SHE NEEDS TO COMPLETE THE JOB. NOT TOO MANY BOXES AND NOT TOO FEW
