the answer is 30 its the sum of all these numbers then divide by 2
The factors of 15 are: 1, 3, 5, 15 The factors of 18 are: 1, 2, 3, 6, 9, 18
The common factors of 15 and 18 are 1 and 3Common factors of 15 and 18 are: 1 and 3.
13: 1, 13 14: 1, 2, 7, 14 15: 1, 3, 5, 15 16: 1, 2, 4, 8, 16 17: 1, 17 18: 1, 2, 3, 6, 9, 18 19: 1, 19 20: 1, 2, 4, 5, 10, 20 21: 1, 3, 7, 21 22: 1, 2, 11, 22 23: 1, 23
The common factors of 18 and 33 are 1 and 3
Common factors of 12, 15, and 18 are: 1 and 3.
If you mean eightieths, 7/80 x 18 = 126/80 = 63/40 = 1 and 23/40 If you mean eighths, 7/8 x 18 = 126/8 = 63/4 = 15 and 3/4
If you mean the fraction 23/15, divide 23 by 15. The whole part will be the whole number; the remainder will be the numerator for the fractional part.
The reciprocal of a number is 1 over the number or 1 divided by the number. EXAMPLE : The reciprocal of 5 is 1/5. The reciprocal of 18.7 is 1/18.7. A fraction can also have a reciprocal : The reciprocal of 1/5 is 5 (or 5/1) The reciprocal of 18/23 is 1/18/23 = 23/18.

5/6 + 4/9 = ? 15/18 + 8/18 = 23/18 or 1 5/18 or 1.28
1, 3, 5, 15 1, 23 The GCF is 1.
4/9 + 5/6 Addition of fractions. [4(6) + 5(9)] / (9x6) [24 +45] / 54 69/54 = 1 15/54 = 1 5/18 The answer!!!!!
The GCF is 1.
20 x (1 + (15/100)) = 20 x 1.15 = 23
The factors of 15 are 1, 3, 5, and 15. The factors of 18 are 1, 2, 3, 6, 9, and 18. The common factors of 15 and 18 are 1 and 3.
The composite numbers from 1 to 23 are 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, and 22.
The factors of 15 are: 1, 3, 5, 15The factors of 23 are: 1, 23
