Like Jay said, remove the common factors. Another way to think of it is:
7/49=
(7 * 1) /( 7 * 7)
Then cancel a seven from both the numerator and denominator, and you get 1/7.

To reduce a fraction (that is, write it in simplest form), you want to look for any factors besides 1 that are common to both the numerator and denominator. Then divide both numerator and denominator by those factors. That's often referred to as "canceling out" the common factor.
In this case, the only non-1 factor of the numerator is 7, and 7 is indeed a factor of 49, so we divide both top and bottom by 7:
7 ÷ 7 = 1
49 ÷ 7 = 7
So the fraction reduces to 1/7. Hope that helps!

No, the 49 would be over 100. The decimal point means 49 100ths. In it`s simplest form it would be 1/7th.
