Answer 1

Answer:

Hi myself Shrushtee.

Step-by-step explanation:

An area model is used to show a representation of multiplication or division. A rectangle is divided into columns and rows to represent the numbers. The product of two numbers is similar to finding the area of a rectangle.

Area of a rectangle=length×width

Here is a multiplication problem involving two decimal numbers.

0.3×0.4

Let’s start by thinking of a decimal using a hundreds grid to represent the hundredths of a decimal.

0.3=0.30 or 30 hundredths 0.4=0.40 or 40 hundredths

Shade 30 squares green vertically because 30 hundredths is also 30 out of 100.Shade 40 squares yellow horizontally because 40 hundredths is also 40 out of 100. Combine the two numbers on the same hundreds grid to see what it would look like to multiply these two decimals together.
