Heis demonstrating another method of finding the fraction of the whole number he used. If 6/6 = 6 then 2/3 = 4/6. Therefore, 2/3 or 4/6 of 6 equals 4 because 4 is 2 out of every 3 in 6. Also, if 3 x 2 = 6, then 2 x 2 = 4 and 2/3 = 4 out of the whole 6
Theorder of multiplication does not matter, but we’ll put the larger of the two numbers on top of the smaller number. The first step is to multiply 5 times 127. Again, we proceed from right to left. So, 5 times 7 is 35. We write the 5, then carry the 3 to the tens column. Next, 5 times 2 is 10.
Leta and b be two whole numbers, according to the commutative property a + b = b + a or a b = b a. Example: Sum, 11 + 7 = 18 and 7 + 11 = 18. Product, 7 × 6 = 42 and 6 × 7 = 42. This property does not hold good for subtraction or division. Example: Difference, 7 – 2 = 5 and 2 – 7 = – 5, which is not a whole number.

Whenyou start using 1,2,3,4 and so on, you are using the counting numbers or to give them a proper title, you are using the natural numbers. Whole Numbers Whole numbers are easy to remember.
Startfrom 3. Since we add 4 to this number so we. make 4 jumps to the right; from 3 to 4, 4 to 5, 5 to 6 and 6. Find 4 + 5; 2 + 6; 3 + 5 and 1+6 using the number line. to 7 as shown above. The tip of the last arrow in the fourth jump is at 7. The sum of 3 and 4 is 7, i.e. 3 + 4 = 7. Subtraction on the number line. CCSSMath.Content.3.OA.A.2. Interpret whole-number quotients of whole numbers, e.g., interpret 56 ÷ 8 as the number of objects in each share when 56 objects are partitioned equally into 8 shares, or as a number of shares when 56 objects are partitioned into equal shares of 8 objects each. For example, describe a context in which a number of F3sE.
