Answer:
direct
Step-by-step explanation:
The standard form of an equation representing direct variation is
y = kx ← k is the constant of variation
The standard form of an equation representing inverse variation is
y = 
← k is the constant of variation
y = - 
x ← represents direct variation with k = -
1. 15 / 1/3
When dividing, the second fraction flips over .
15* 3/1= 45/1= 45
2. 24 / 1/6
24*6= 144
4. 7/12 / 1/3
7/12*3/1
Cross out 3 and 12, divide by 3
12/3= 4
3/3= 1
7/4* 1/1. Multiply the numerator together. Multiply the denominators together.
7*1= 7
4*1= 4
7/4 or 1 3/4
Answers :
1. 45
2. 144
4. 7/4 or 1 3/4

The 5x5 square grid has 6 , 2 x 2 subgrids and the least value of n for which you can be certain that it will have a 2 x 2 subgrid of grey squares is 12.
<h3>What is a Square ?</h3>
A square is a polygon with four sides and all the sides are equal and parallel and all the angle value is 90 degree.
(a) The 5x5 square grid has 6 , 2 x 2 subgrids.
(b) the least value of n for which you can be certain that it will have a 2 x 2 subgrid of grey squares is 12
as it can be understood from the figure 2 that only the last square doesn't have a pair and the rest all does
more than that will be extra but 12 will be enough to make all the grey squares of 2 x 2 subgrid .
