Yes they can cause i said they could
You can write any fraction greater than 1 as a mixed fraction. It is not customary to use mixed fractions for ratios.
fractions can't be written as a mixed number because it's already a fraction but im not sure about ratios.
Equivalent ratios are ratios that represent different numbers but the relationship between the numbers is same.
This is because the average of the ratios does not take account of the sizes of the numbers in the ratios.
No, its the opposite. Compounds have fixed ratios, think of H20, while mixtures can vary. You can make many types of mixtures out of the same things. Because of bonding compounds have fixed ratios.
ratios r comperisons between 2 numbers
Numbers
Yes, they are.
Yes, they often are. Gear ratios and anatomical ratios are usually expressed in decimal numbers in relation to one.
you dont
These are the numbers which cannot be expressed as ratios of two integers.
Yes - except that you need to specify ratios of INTEGERS. pi/2 is a ratio of pi and 2 but it is irrational.
