To find the scale factor from 7 cm to 1 m, first convert 1 meter to centimeters, which is 100 cm. Then, divide the larger measurement by the smaller one: ( \frac{100 \text{ cm}}{7 \text{ cm}} \approx 14.29 ). Therefore, the scale factor is approximately 14.29:1.

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
To convert 7 feet by 5 feet into centimeters, you can use the conversion factor of 1 foot being equal to 30.48 centimeters. Therefore, 7 feet is approximately 213.36 centimeters, and 5 feet is about 152.4 centimeters. Thus, a size of 7'x5' is approximately 213.36 cm by 152.4 cm.
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.
