Why do all square numbers have an odd number of factors?
Because if you think about it, a square number has two factors that are the same. For example, look at the number 16. Its factors are 1, 2, 4, 8, and 16. 1 and 16 go together, 2 and 8 go together, and then 4 gets paired up with another 4.

4
What is one half plus one fourth plus one eight plus one sixteenth?
1/2 + 1/4 + 1/8 + 1/16 We need to multiply those so all the denominators (bottom numbers) are the same (16). 1/2 * 8/8 + 1/4 * 4/4 + 1/8 * 2/2 + 1/16 8/16 + 4/16 + 2/16 + 1/16 Now we add the numerators and keep the same denominator. 12/16 + 3/16 = 15/16
How do you add fractions when the bottom numbers are the same?
The bottom number remains the same 1/4 + 3/4= 4/4 = 1 3/8 + 1/8 = 4/8 = 1/2 2/16 + 7/16 = 9/16
What would the number be if the first two consecutive factors have the same sum as the number?
15 and 16. 15= 3*5. 3+5=8 16= 4*4. 4+4=8
What fractions are equivalent to four over nine?
Fractions are equivalent when you multiply (or divide) the top and bottom number by same amount. So 4/8 is same as 2/4 is same as 8/16 Therefore 4/9 is same as 8/16 is same as 40/90 ....
