Short Answer

Expert verified

The product is−11.16.

Step by step solution

01

Step 1. Concept of the product of like and unlike sign integers.

The product of two integers with the same sign is always positive.

The product of two integers with opposite signs is always negative.

02

Step 2. Concept of multiplication of decimal numbers.

First, multiply the numbers normally as whole numbers then count the total number of digits after the decimal in each number and place the decimal point before the same number of digits from right to left in the resultant product.

03

Step 3. Evaluate the product.

Since, the decimal count is 2 from both fractions,

thus

=-11.16

Therefore, the product is−11.16.
