Let first COI=n=3 second COI=n+2=5 third COI=n+4=7 (n)(n+2)=n+4+8 check: n^2+2n=n+12 n^2+n-12=0 -n-12 -n-12 -4^2+(-4)-12=0 n^2+2n-n-12=0 16+(-4)-12=0 n^2+n-12=0 12-12=0 (n+4)(n-3)=0 0=0 n+4=0 n-3= 0 n^2+n-12=0 -4 -4 +3 +3 3^2+3-12=0 n=-4 n=3 9+3-12=0 reject 12-12=0 because is negative and it needs to be positive 0=0
1/3 + 1/4? 1/3 can be changed to 4/12.. 1/4 can be changed to 3/12.. 3/12 + 4/12 = 7/12 you can't simplify 7/12, so your final answer is 7/12.
12 + 23 + 14 + 11 = 60/4 = 15 The average is therefore 15.
4*12 + 3*23 = 117.
It is: 12-12 = 0

69/12 = (23×3)/(4×3) = 23/4 = (5×4+3)/4 = 5¾

4 x 3 = 12. Therefore, any number less than 12 is less than the product of 4 and 3.
The product of 4 and 3 is 12. You can use a calculator or you could do 4+4+4= or 3+3+3+3= and you will get 12. The properties of multiplication is that if you switch the beginning two numbers around, the product of the two numbers will not be impacted by the change.

The HCF is 4. 16/4 is 4, 12/4 is 3
5/4 x 3/3 = 15/12 23/12 - 15/12 = 8/12 = 4/6 = 2/3 Two thirds
