Partial products is breaking down every number in multiplication and adding them. Regrouping is grouping numbers then adding them. They are alike because they both involve breaking down numbers and then adding them. They are different because Partial products is taking all the numbers broken down, while Regrouping is just a couple of the number.
Answer:
1,2, and 4 are all repeating 3 is non repeating
Step-by-step explanation:
To multiply a whole number by a fraction less than one, you have to rewrite the whole number in the expression as a fraction by putting a one under it.
For example, in 10 x 2/5, you would rewrite the 10 to 10/1 x 2/5.
Then, you would multiply the top and bottom of the two fractions. In this case, it would be 10 x 2 and 1x5. This would result in 20/5.
Finally, you would simplify this fraction by dividing. The final answer is 4.
