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
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.
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.
7 kilometers is 700,000 centimeters.
