This tutorial goes over question 64 from chapter 1 section to practice.
00:07
And we're told to perform the given operations and simplify if possible.
00:12
So our operation here is addition and the denominators are not the same in our fraction.
00:17
And that means we need to build fractions with equivalent fractions with a common denominator.
00:22
And that means that we need to figure out what our common denominator is.
00:27
So there's a couple ways you can do this.
00:29
You may just know it.
00:30
You may want to list factors.
00:33
You may want to do the prime factorization.
00:36
But i am simply going to list these factors because i happen to know, i mean the multiples, because i happen to know what it is.
00:44
And it's going to be a little faster.
00:45
So 25 and 10, produce times 1 times 2.
00:52
And then 10 times 5 is 50.
00:56
Is your 10, 20, 30, 40, 50...
