Question

Find the product or quotient

(2.5)(7.1)

Short answer

The value of the product (2.5)(7.1) is 17.75

Step-by-step solution

Step-1 – Apply the concept of product

In mathematics, a product is the result of multiplication, or an expression that identifies factors to be multiplied. The numbers that are being multiplied are called the factors and the product of two numbers is the result you get when you multiply them together.

Step-2 – Example for the product

For example, 30 is the product of 6 and 5.

$30= 6 · 5$(The two factors are 6 and 5)

$26= 2 · 13$(The two factors are 2 and 13)

Step-3 – How to place the decimal point in multiplication 

To multiply decimals, first multiply as if there is no decimal. Next, count the number of digits after the decimal in each factor. Finally, put the same number of digits behind the decimal in the product.

Step-4 – Evaluate the expression

Evaluate the product: (2.5)(7.1)

${\begin{array}{l}25\\ x\underset{\_}{71}\\ 25\\ +\underset{\_}{1750}\\ 1775\end{array}}_{{}_{}}$

Decimal point should be after two digits from right to left.

The product: (2.5)(7.1) = 17.75
