Answer 1

to do these problems, it helps to learn some rules for what numbers divide into another number.

if a number ends in an even digit i.e. in 0,2,4,6,8
then you can divide it by 2

can you use that rule? does 2 divide into both the top and the bottom ?

Answer 2

ya

Answer 3

what do you get ?

Answer 4

11/15

Answer 5

there are other rules. You should memorize the ones for 2,3,4,5,6,9

the other thing to learn are the first few prime numbers because once you get one, you can't simplify any more.

Answer 6

can 11 be divided?

Answer 7

Here are the primes less than 100
as you can see , 11 is on the list, so only 11 and 1 divide into 11
we are done: 11/15 is as simple as you can get
if you had
12/15
then by the "3" rule:1+2= 3 and 1+5= 6 means both can be divided by 3
we get 4/5
5 is prime. so that would the the answer.


2 3 5 7 11 13 17 19 23
29 31 37 41 43 47 53 59 61 67
71 73 79 83 89 97 101

Answer 8

if you learn that list, and the rules, you will be ahead of everybody in your class.
