There are two of theme dudgeon
Answer:
2 * 21
3 * 14
6 * 7
Step-by-step explanation:
7 * 2 = 14
56 - 14 = 42
Multiples of 42 = 2,3,6,7, 14, 21
Because you need to have the same denominators to subtract fractions, you need to find the LCM of 15 and 9. The LCM of 15 and 9 is 45. Because 15 goes into 45 3 times, you multiply 2* 3 to find the numerator. Because 9 goes into 45 5 times, you multiply 5*5 to find the numerator. The new equation is 25/45 - 6/45. The answer is 19/45, which cannot be simplified any further.
