Number 1, find the LCM for each pair of numbers. Remember, the LCM stands for Least Common Multiple. To find the Least Common Multiple of 4 and 6, you should draw a capital “M” on your paper. We will call this the M Chart. At the top of one side of the M Chart, write the number 4, and on the other side, write the number 6. Let’s begin. We will begin by writing the first 6 multiples of 4. These are: 4, 8, 12, 16, 20, and 24. Now let’s write the fist 6 multiples of 6. These are: 6, 12, 18, 24, 30, and 36. Now let’s compare those multiples. The LCM of 4 and 6 is 12. Let’s use the same strategy to find the LCM of 3 and 12. We will once again begin with an M Chart. We will put 3 at the top of one side and 12 at the top of the other side. Let’s once again practice writing the first 6 six multiples of 3 and 12. The first 6 multiples of 3 are: 3, 6, 9, 12, 15, and 18. Now we will list the first 6 multiples of 12. They are: 12, 24, 36, 48, 60, and 72. Now compare the multiples. 12 is once again the LCM.
Let’s look at number 2. Our directions say to add or subtract. Let’s look at our first set of mixed numbers. We have 3 ¼ minus 1 ¾. To solve, change each mixed number to an improper fraction and subtract. 3 ¼ can be renamed to 13/4, and 1 ¾ can be renamed to 7/4. 13/4 minus 7/4 equals 6/4. To complete the problem, 6/4 should be written in its simplest form. The final answer is 1 ½.
