Answer 1

Answer:

a)1/5 b)9/10

Step-by-step explanation:

a)20/100=2/10=5

b)90/100=9/10

Answer 2

a) 20%

$20\% \: = \frac{20}{100} = \frac{1}{5}$

Explanation:

A number given as a percent is actually a fraction already - the denominator is out of 100.

$20\% = \frac{20}{100}$

Now change it to its simplest form by dividing the top and bottom by the HCF, which is 20.

$\frac{20}{100} \div \frac{20}{20} = \frac{1}{5}$

b) 90%

So we know that percentage, is a fraction itself.

$90\% = \frac{90}{100}$

Simplify this and it becomes:

$\frac{9}{10}$
