The factors of 9 are 1, 3, 9 The factors of 16 are 1, 2, 4, 8, 16 The common factor of 9 and 16 is 1

3/4 + 2 1/4 + 3/4 + 9/16 ~ Begin by making all mixed numbers improper fractions 2 1/4 --> (2*4+1)/4 --> 9/4 3/4 + 9/4 + 3/4 + 9/16 ~ Next, make all denominators the same by finding a common denominator (in this case, 16) 3/4 * 4/4 --> 12/16 9/4 * 4/4 --> 36/16 3/4 * 4/4 --> 12/16 12/16 + 36/16 + 12/16 + 9/16 ~ Now add all of the numerators (12+36+12+9)/16 (69)/16 69/16 Either leave the answer as 69/16 or use a calculator to find: 4.3125

The factors of 16 are 2, 4 and 8. The factors of 36 are 2, 4, 9, 12 and 18. The common factors are therefore 2 and 4. The common prime factor is 2.

9/16 + 1/4 = 9/16 + 4/16 = 13/16.

Example: 3/4 - 9/16 = ?/? You have to find the lcm/THE LEAST COMMON MULTIPLE 4: 4,8,12,16,20,24.... 16: 16....
