Convert to the same units, drop the units and simplify:
1 m = 1000 mm
8 mm : 1 m
= 8 mm : 1000 mm
= 8 : 1000
= 8÷8 : 1000÷8
= 1 : 125
It is 1 to 125.
Length of image = Length of original*Scale factor = 10*8 = 80 yards.

big/small so if it was 1/4 2/8 divide to numbers across 8/4 and 2/1 i THINK
Try it out. The volume of a 2-inch cube is 8 cubic inches. The volume of a 4-inch cube is 64 cubic inches. The dimensions doubled, the volume increased 8 times because volume is a cubic measure. 2 cubed is 8.
Length of image = Length of original*Scale factor = 10*8 = 80 yards.
Answer: Since you are looking for the scale factor of ABC to DEF the answer is 8 because DEF is 8 times larger than ABC.
It is: 2 to 3
2:3
It is: 2 to 3
1 1/2
8/11

It depends where the centre of enlargement (dilation) was; it can be any value.As all you have given us is the change in the coordinate of the A vertex, so all we can conclude is that the centre of enlargement is somewhere along the line y + 2x = 0.Examples:If the centre is at (3, -6) then the scale factor is -6If the centre is at (0.5, -1) then the scale factor is -1If the centre is at (0, 0) then the scale factor is -3/4If the centre is at (-3, 6) then the scale factor is 0If the centre is at (-4, 8) then the scale factor is 1/8If the centre is at (-10, 20) then the scale factor is 1/2If the centre is at (11, -22) then the scale factor is 2If the centre is at (1.4, -2.8) then the scale factor is 6(As the centre tends towards ±∞ the scale factor tends towards 1 [from below towards -∞, from above towards +∞].)
8
If you mean: 8 12 16 and 10 15 20 then it is 4 to 5
Scale factor: 2 to 1
