8 x 5 - 4 = 36 cubes
There is a possibility you mean 8^3 x 5^3 - 4^3 which would be 512 x 125 - 64 = 63936 but that would be "cubed" rather than "cubes."

minus 4 is bigger because minus 5 is further away from naught that minus 4 is
-5 minus 4 is -9.
(-4)-(-5)+(-8) =-4+5-8 = -7
24 ; 72; 18; 23; 17.
6 - 5 + 7 * 4 - 3
4 - 5 + (-2) = -3

Use the greatest common factor of 5 and 4 (20). Next, because whatever you do to the numerator you have to do to the denominator, you would multiply the 4 in 4/5 by 4 (because 5*4=20) and multiply the 1 in 1/4 by 5 (because 4*5=20). What you should have after you apply this method should be 16/20 - 5/20, which equals 11/20. Therefore, 4/5 - 1/4 = 11/20. Hope this helps!
