5*63/7=x
Simplify.
5*63/7=5*9=45
x=45
5/7 + 7/9 = 45/63 + 49/63 = 94/63 or 1 31/63
-100/63 ÷ 10/81 = -90/7 or -126/7

45/63 is 5/7 simplified
(7/9) x (4/63) = (1/9) x (4/9) = 4/81
5/9 + 5/7 = 35/63 + 45/63 = 80/63 or 1 20/63
5/7 + 7/9 = 45/63 + 49/63 = 94/63 or 1 31/63
(63/7) / (22/14) = (63/11) meaning that it equals 63 over 11
3/7=x/63 189=7x 27=x
-100/63 ÷ 10/81 = -90/7 or -126/7
5 / 7 + 5 / 9 lowest common denominator = 63, so 45 / 63 + 35 / 63 = 80 / 63 = one and seventeen sixty thirds ( 117/63
To find how many eights are in 63, you divide 63 by 8. The result is 7 with a remainder of 7, meaning there are 7 complete eights in 63, which equals 56. Thus, 63 contains 7 eights, with 7 left over.
