Question

1. using whole numbers and decimal place shifts: a. find the product of 53 and 87.

Explanation:

Step1: Rewrite 53 as a decimal shift

$53 = 5.3 \times 10^1$

Step2: Rewrite 87 as a decimal shift

$87 = 8.7 \times 10^1$

Step3: Multiply the adjusted numbers

$5.3 \times 8.7 = 46.11$

Step4: Multiply the powers of 10

$10^1 \times 10^1 = 10^{2} = 100$

Step5: Combine the two results

$46.11 \times 100 = 4611$

Answer:

4611
