Question

find the product.
81 × 0.01 = ?

Explanation:

Step1: Recall the meaning of multiplying by 0.01

Multiplying a number by 0.01 is equivalent to dividing the number by 100, because \(0.01=\frac{1}{100}\). So, \(81\times0.01 = 81\times\frac{1}{100}\).

Step2: Perform the division

Dividing 81 by 100 means moving the decimal point two places to the left in 81. Since 81 can be written as 81.0, moving the decimal point two places left gives 0.81.

Answer:

0.81
