Answer :
To solve the problem using the product of 221 \times 4, let's first understand the relationship between the numbers involved.
The given product is $221 \times 4 = 884$.
Now, let's solve $2.21 \times 4$ using this product:
Recognize the relationship: Notice that $2.21[tex]is $100[/tex] times smaller than $221[tex]. In other words, $2.21 = \frac{221}{100}[/tex].
Use the given product: We already know that $221 \times 4 = 884$.
Calculate the new product: Since $2.21[tex]is[/tex]\frac{1}{100}[tex]of $221[/tex], we can compute the product $2.21 \times 4[tex]by dividing $884[/tex] by $100$:
[tex]\frac{884}{100} = 8.84[/tex]
Therefore, $2.21 \times 4 = 8.84$.
This explains step-by-step how you can use the product of $221 \times 4[tex]to find the result of $2.21 \times 4[/tex] by adjusting for the decimal point of the smaller number.
