Answer :

To find the product of two numbers means to multiply them together. Let's solve each of the multiplication problems step-by-step.

  1. 847 \times 3

When multiplying, align the numbers vertically and calculate as follows:

[tex]\begin{array}{c}
\phantom{+}847\\
\times\phantom{+} 3 \\
\hline
\phantom{+}2541
\end{array}[/tex]

So, 847 times 3 equals 2,541.

  1. 987 \times 8

Similarly, multiplying through we get:

[tex]\begin{array}{c}
\phantom{+}987\\
\times\phantom{+} 8 \\
\hline
\phantom{+}7896
\end{array}[/tex]

So, 987 times 8 equals 7,896.

  1. 855 \times 6

Continuing with the same process:

[tex]\begin{array}{c}
\phantom{+}855\\
\times\phantom{+} 6 \\
\hline
\phantom{+}5130
\end{array}[/tex]

So, 855 times 6 equals 5,130.

  1. 968 \times 5

Multiplying through:

[tex]\begin{array}{c}
\phantom{+}968\\
\times\phantom{+} 5 \\
\hline
\phantom{+}4840
\end{array}[/tex]

So, 968 times 5 equals 4,840.

  1. 385 \times 4

Carrying out the multiplication:

[tex]\begin{array}{c}
\phantom{+}385\\
\times\phantom{+} 4 \\
\hline
\phantom{+}1540
\end{array}[/tex]

So, 385 times 4 equals 1,540.

  1. 988 \times 8

Calculating the product:

[tex]\begin{array}{c}
\phantom{+}988\\
\times\phantom{+} 8 \\
\hline
\phantom{+}7904
\end{array}[/tex]

So, 988 times 8 equals 7,904.

  1. 648 \times 8

Find the product as follows:

[tex]\begin{array}{c}
\phantom{+}648\\
\times\phantom{+} 8 \\
\hline
\phantom{+}5184
\end{array}[/tex]

So, 648 times 8 equals 5,184.

  1. 587 \times 7

Proceeding with the multiplication:

[tex]\begin{array}{c}
\phantom{+}587\\
\times\phantom{+} 7 \\
\hline
\phantom{+}4109
\end{array}[/tex]

So, 587 times 7 equals 4,109.

  1. 775 \times 9

Let's compute this product:

[tex]\begin{array}{c}
\phantom{+}775\\
\times\phantom{+} 9 \\
\hline
\phantom{+}6975
\end{array}[/tex]

So, 775 times 9 equals 6,975.

  1. 758 \times 7

By multiplying we get:

[tex]\begin{array}{c}
\phantom{+}758\\
\times\phantom{+} 7 \\
\hline
\phantom{+}5306
\end{array}[/tex]

So, 758 times 7 equals 5,306.

  1. 881 \times 9

Finding the product gives:

[tex]\begin{array}{c}
\phantom{+}881\\
\times\phantom{+} 9 \\
\hline
\phantom{+}7929
\end{array}[/tex]

So, 881 times 9 equals 7,929.

  1. 453 \times 2

Finally, the product is:

[tex]\begin{array}{c}
\phantom{+}453\\
\times\phantom{+} 2 \\
\hline
\phantom{+}906
\end{array}[/tex]

So, 453 times 2 equals 906.

Each of these calculations demonstrates the process of multiplication by aligning digits according to place values and summing appropriately to calculate the total product.
