Answer:
C
Step-by-step explanation:
Any fraction with a denominator of 0 is irrational.
You use the Pythagorean theorem and square 3 and 4. You then get 9 and 16. Add both to get 25. The square root of 25 is 5 so 5 is your answer
Answer:
see below
Step-by-step explanation:
yes it matters, if you don't know how to write a repeating decimal as a fraction you can use this trick
let's say we don't know what it is
0.33333333...
so we see that there's only one repeating digit
so the answer is
(the repeating digit)/(9)=3/9
and that simplyfies to 1/3
let's try another one
0.67676767...
as you can see know the repeating is 67
so the answer is
(the thing that repeats)/(99)=67/99
do you see a pattern?
when we have a number x of repeating decimals
the denominator of the fraction (the thing that's down) is 9999..99 in there must be x 9's
let me explain
if you have 3 repeating decimals
the denominator will be 999
you see 3 nines
and so on.
