A sum.
The two (not tow) numbers with a sum of 12 and a quotient (not quotation) of 3 are 9 and 3.
Factor them.
When the numbers are co-prime, ie have no common factor. Simplest example is 2 & 3 whose LCM is 6
You need at least tow numbers to find an LCM. If that's 4 and 12, the LCM is 12.
To find the LCM of two numbers you need to multiply them together and then divide by the HCF. In this case, the numbers are coprime and so the HCF will be 1. Therefore was just have to multiply the numbers together: 7x3 = 21 And so the LCM of 7 and 3 is 21.
7 and 8
Subtracting two numbers is finding their difference.
7 and 8
No.
9 and 8 if you add them.
