18/11 x 5/12 is 15/22
22 -12-------=10
The product of w and 12 is 12w.
The product of 8 and 12 is 96
22 x 22 = 484 22 + 22 = 44
12 = 22 x 3
12 = 22 x 3
18/11 x 5/12 is 15/22
The GCF is 2.
12 = 2 x 2 x 3Alternatively, using power notation:12 = 22 x 32 x 2 x 3 = 12
You need to look for 2 numbers which have a product of 156 and a difference of 1. First 156 can be written as a product of it's prime factors: 156 = 22 x 3 x 13. From this you can see that 22 x 3 = 12 and hence 12 x 13 = 156.
The product of 11 times 2 is 22
The product of 12 and 12 is 144.
