When dividing fractions, multiply by the inverse of the fraction.

That is, a/b divided by x/y = a/b times y/x = ay/bx

For example,

2/5 divided by 3 = 2/5 x 1/3 = 2/15

2/5 divided by 1/3 = 2/5 x 3/1 = 6/5

5 divided by 3 = 5/1 x 1/3 = 5/3

5 divided by 1/3 = 5/1 x 3/1 = 15/1 (= 15)

Can subscripts in a chemical formula be fractions?

The Subscripts in a Chemical formula explain how the atoms in that compound are chemically bonded. As a fraction of an atom cannot bond, the subscripts cannot be fractions. Coefficients, however which go before a chemical formula in chemical equations may be fractions. This is because they explain the ratio of the number of moles of each species required for the reaction and it is possible to have a fraction of a mole of something.

How do you cancel out the number 12 and 32 in multipling fractions?

The answer does depend on where in the question the 12 and 32 appear. But 12 and 32 have 4 as their highest common factor. So, assuming that 12 is on the top and 32 is on the bottom, 12/32 times something = 3/8 times the same something.


How many 75 kg in 1 Newton?

The formula is simple. You can get the Newton force by multipling the mas and the accelaration. F = m.a, so in this case the accelaration is the gravity which is 9.8 m/s. The answer is F = 75kg . 9.8m/s = 735N.
