Modeling Decimal Multiplication
Use decimal grids or area models to find each product.
0.3 x 0.5
03
0.3 x 0.5 represents 0.3 of 0.5. Shade 5 rows
of the decimal grid to represent 0.5
Shade 0.3 of each 0.1 that is already shaded
0.5
to represent 0.3 of
square(s) are double shaded.
This represents hundredth(s), or 0.15.
0.3 x 0.5
B 3.2 x 2.1
3.2
Use an area model. In the model, the large
squares represent wholes, the small rectangles
along the right and lower edges represent tenths,
and the small squares at the lower right represent
2.1
hundredths. The model is 3 and 2 tenths units long,
and 2 and 1 tenth unit wide.
The area of the model is
whole(s) + tenth(s) + hundredth(s) square units.

1. Analyze Relationships How are the products 2.1 x 3.2 and 21 x 32
alike? How are they different?

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
