Asked by I dunno
what is an eay way to add 1/5 1/2 and 1/7. I have to find a number that they all go into for a similar denominator right? but how do I do that without taking forever.
Multiply the denominators:
5 x 2 x 7 = ??
=)
As Writeacher has noted, the common denominator is 70 in this case. Convert each fraction to the equivalent value with 70 as the denominagtr, and add them.
1/5 = 14/70
1/2 = 35/70
1/7 = 10/70
