<PRE><B>Question 280177</B>
how do I build up fractions like 5/7 = ?/98 do not understand how to do this please explain
-------------------------
5/7 = ?/98
-----------
What was 7 multiplied by to become 98?
Answer: 7x = 98
x = 14
--------------------
So, multiply numerator and denominator of 5/7 by 14 to get:
(5/7)(14/14) = 70/98
