Question

Part 1. How did you compute sums of dollar amounts that were not whole numbers? For example, how did you compute the sum of $5.89 and $1.45? Use this example to explain your strategy.

Part 2. How did you compute products of dollar amounts that were not whole numbers? For example, how did you compute the cost of 4 pounds of beef at $5.89 per pound? Use this example to explain your strategy.

Answer 1

The answer is below

Explanation:

1) When you are computing the sums of numbers, you do not round up. You have to be exact.

Summing numbers involves you adding the numbers together as well as their decimals. Therefore:

$5.89 + $1.45 = $7.34

2) When you are computing the product of numbers, you do not round up. You have to be exact.

The product of numbers involves you multiplying the numbers together. Therefore:

$5.89 per pound * 4 pounds of beef = $23.56
