And so you distribute the negative sign. And so now we can worry about the whole number parts, 7 minus 3. Well, 7 minus 3 is going to give us 4. So that's going to give us 4. So this is going to be the same thing. And I think the least common multiple of 9 and 5 is going to be Literally, you then multiply.
They have no common factors. So it's going to be over To go from 9 to 45, I have to multiply by 5. So I'm going to have to multiply the numerator by 5. So 6 times 5 is Then I'm going to subtract.
