Question 879315
How many of 30*30 are in 800*700?  The tile area units kept as square centimeters, and the room unit converted to square centimeters.


{{{(800*700)/(30^2)=(56/9)(10000/100)}}}
{{{100(56/9)}}}
{{{(6&1/9)*100}}}
{{{highlight(611&1/9)}}}, probably the one-ninth is small enough to ignore.  Maybe easy enough to cut the right piece to fill what is empty.
