Cross Products Property of Proportions states that the product of the means is equal to the product of extremes.
i,e
Also, in the proportion the first (a) and the last terms(d) are called the extremes, whereas the second(b) and the third terms(c) are called the means.
Given the proportion:
First term = 1
Second term = 2
Third term = 4
Fourth term = 8
By definition;
The product of means =
The product of extremes =
Therefore, the product of both the means and the extremes is, 8
the means are y and z
the extremes are x and t
we have
1:2=4:8
means=2 and 4
extrememes=1 and 8
product of means=2 times 4=8
the product of extremes=1 times 8=8
the answer is 8

What is Unitary Method?
The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Dan painted 3/4 of a wall using 1/4 of a can of paint.

Answer:
The correct option is;
(x, y) → (215·x, 215·y)
Step-by-step explanation:
An enlargement is a form of transformation involving an alteration of the size of the shape. When a shape is to be enlarged, the center of the shape is noted and the enlargement of the dimensions of the shape from that center is by multiplication of each point by the factor of the enlargement or the scale factor.
Therefore, based on the requirement for enlargement, and given the dimension of the point from the center as (x, y) the enlargement then is (215·x, 215·y), where 215 is the scale factor.
Answer:
A. (x, y) → (215x, 215y)
Step-by-step explanation:
Enlargement of a figure is the process of increasing the size of a given figure by the use of a scale. It requires the use of a scale factor that is greater than 1 to form an image. This is called dilation in transformation.
Transformation is the process of manipulating the size or orientation of a figure. To enlarge a shape, a center of enlargement is required.
Thus, the rule that signifies enlargement of a figure is ;
(x, y) → (215x, 215y)
This implies multiplying the initial coordinate x and y by a factor of 215 to produce a required size of an image.
