Question

Help!1. Change 80% to a fraction 2. Change 3/8 to a percent

Answer 1

1.

80% means eighty out of every hundred.

This way, the fraction would be:

`(80)/(100)`

Simplifying,

`(80)/(100)\rightarrow(8)/(10)\rightarrow(4)/(5)`

Note: Notice that eighty out of every hundred, eight out of every ten and four out of every five mean all the same: 80%

2.

3/8 means three out of every eight. To convert this to a percentage we can use a rule of three, taking 8 as the 100% as following:

This way,

`\begin{gathered} x=(3\cdot100)/(8) \\ \rightarrow x=37.5 \end{gathered}`

Therefore, 3/8 as a percentage would be 37.5%
