Explain how to draw a picture to find 3 x 0.9. Grandma needs help for her 5th grade granddaughter!
One way to do this is to draw three rectangles. Divide each into 10 equal sections. Shade 9 of each 10 sections.
To draw a picture to find the product of 3 multiplied by 0.9, you can use rectangular arrays or circles. Let's use rectangular arrays for this explanation.
Step 1: Draw a rectangle to represent the first number, which is 3.
Step 2: Divide this rectangle into three equal columns, representing the value of 3.
Step 3: Now, within each column, divide the rectangle into 10 equal rows, representing the decimal value of 0.9.
Step 4: Shade 9 rows in each column to show the value of 0.9.
Step 5: Count all the shaded squares. In this case, we have 27 shaded squares.
Step 6: The number of shaded squares represents the product of 3 multiplied by 0.9. Therefore, 3 x 0.9 = 27.
By visually representing the multiplication problem using a rectangular array, it helps to understand the concept of multiplying a whole number by a decimal.
