Nine-tenths of five-ninths is equal to one-half.
32 + 52 = 9 + 25 = 34
4/10 + 5/10 = 9/10
if s is 2, 2s is 4. 3 squared is 9. 4 + 9 = 13. 13 / 5 = 2.6, which is not equal to 2.
(2*2*2)+2/2=9
4s2 - 9 can be expressed by using the identity: a2 - b2 = (a-b)(a+b) Therefore, 4s2 - 9 = (2s)2 - 32 = (2s-3)(2s+3)
8/8 (8/8 + 8) = 9
99 + 9(9-9)
The denominator (bottom number) of a fraction tells you the number of equal parts (in a whole); The numerator (top number) of a fraction tells you how many of those parts. You have five parts out of 9 equal parts which is 5/9
5/9
6s+2s=72 combine like terms 6s+2s=8s set equal to 72 8s=72 divide both sides by 8 to solve for "s". 8s=72 8 8 your answer is s= 72/8 which is 9.

9/5*5 = 9 since 5/5 is equal to one. 9/(5*5) = 9/25 or 0.36.
