scale factor=7/3.5=2
if your looking up what the scale factor of 3 over 7 u must be dumb
25:1
1/84
Convert to the same units, drop the units and simplify: 1 yd = 36 in → 7 in : 1 yd = 7 in : 36 yd = 7 : 36
It is: 21/12 = 7/4
Take the 'reciprocal' of the given scale factor to go the other way. The 'reciprocal' of a number is 1/(the number). 3 ==> 1/3 5 ==> 1/5 1/7 ==> 7 2/3 ==> 3/2 etc.
1 nm = 10-7 cm
Convert to same units, then the units cancel and the numbers can (possibly) be simplified: 1 m = 100 cm → 7 cm : 1 m = 7 cm : 1 x 100 cm = 7 : 100 (cannot be simplified as no common factor other than 1) If a scale factor of the form 1 : ... is required, then continue by dividing both sides by 7: 7 : 100 → 1 : 14 2/7 ≈ 1 : 14.29
The size of a 7-inch screen in centimeters is approximately 17.78 cm. This is calculated by converting inches to centimeters using the conversion factor of 1 inch equaling 2.54 cm.
To find the scale factors of two objects, you need to compare the ratios of things like their sizes, areas, volumes, and length. For example, if one is given a volume of 7 for a shape, and a second shape has a volume of 14, you have to compare the volume ratio of these two shapes to find the scale factor. This scale factor is 1 to 2, or the volume of the second shape is twice the first one. Scale factors are useful for scale drawings.
Scale factor: 2 to 1
