Answer 1

Answer:

1. 867.3, 2. 507.6, 3. 745.2

Step-by-step explanation:

Partial products with decimals is rather simple. It involves breaking a factor down, preferably the smaller one, and for your case, into ones and tenths. Remember to keep the same digits (ones, tenths) together in their own rows so you don't confuse them!

1. 413*2.1 could be split into 413(2+0.1). 413*0.1 is simply 41.3, and 413*2 is 826. 41.3+826, your PARTIAL PRODUCTS, equal to 867.3.

2. 423*1.2 could be split into 423(1+0.2). 423*0.2 is 84.6, and 423*1 is just 423. 84.6+423, your PARTIAL PRODUCTS, equal to 507.6.

3. 621*1.2 could be split into 621(1+0.2). 621*0.2 is 124.2, and 621*1 is just 621. 621+124.2, your PARTIAL PRODUCTS, equal to 745.2.

Hope this helps! Stay healthy!

Answer 2

Answer: The first answer is 867.3, the second is 507.6, and the final answer is 745.2.

Step-by-step explanation:

This is alot like multiplying using partial products, just your final answer needs to have a decimal at the end. Count how many decimal digits there are, and then shift the decimal that many digits to the left on your answer.
