Because the ratio would;t be correct.
Look at this example. What is the ratio of 1cm to 1 metre?
If you went by these measurements you would get 1:1 which means 1cm is the same as 1 metre., which is false.
The correct answer means comparing 1cm with 100cm (or 1 metre) which is 1:100.
So it's really important with ratios that the units are the same.
In a fraction they must be in the same units. In a ratio they need not be.
Yes. EX) 12/5 = 2.4
Unit Ratio- a ratio that has a denominator of 1
Yes. EX) 12/5 = 2.4
Just convert the units to a common unit. Reminder: 1 meter = 100 centimeters. Then express as a ratio of the same unit. The units cancel in this case.
In a fraction they must be in the same units. In a ratio they need not be.
blank = unit.
The value of the ratio is the same.
Yes. EX) 12/5 = 2.4
Yes. EX) 12/5 = 2.4
Unit Ratio- a ratio that has a denominator of 1
For two measurements to be a conversion factor, they must represent the same quantity but in different units. The ratio should equal 1 and can be written as a fraction where the units cancel out, allowing you to convert from one unit to another.
It is 56 per day.
Yes. EX) 12/5 = 2.4
scale factor
There is no "unit". It is a ratio. Just pick a unit. Since you're likely talking about engine displacement, liters are a good unit to use. +++ Engines are described in litres, but individual cylinder volumes are normally expressed in cubic centimetres (c.c.), but the compression-ratio is the same irrespective of measurement units because a ratio is dimensionless.
there have no unit because both the quantites cancel out each other same as mecghanical advantage there have no unit because both the quantites cancel out each other same as mechanical advantage
