First you are going to put 63 over x (63/x) then you are going to put 90 over 100 (90/100). Then you are going to put them so that they equal each other (63/x = 90/100) and cross multiply so that it looks like this: 6,300 = 90x. then you are going o divide 6,300 by 90 which is 70. so 63 is 90% of 70.
