We're literally just comparing 200 to 800 here.
800 is 4× bigger than 200, of course.
To put that in a percent...
Well, 1 = 100%. (it's a whole)
So 4 = 400%
Factor the numbers, starting from the smallest:
792=2*3*3*11*4
990=2*3*3*11*5
the greatest whole number that can be divided by both 792 and 990 is 2*3*3*11=198
the smallest whole number that can divide both 792 and 990 exactly is 2*3*3*11*4*5=3960
Not sure which one you are asked to find.
First we have to multiply the numerator and the denominator by 5:
=
0.35
Consider this option:
11) 360-(95+32)=233; answer D;
14) if 2x+2=x+11, then x=9, and y-2=9+2, y=13; answer A.
