Question

Nuclear power provided 78% of the energy used in france in 2005. Write 0.78 as a fraction in simplest form.

Answer 1

Here we are given first that Nuclear power provided 78% of the energy used in france in 2005.

Now this was written in decimal as 0.78.

Then we have to write it in fraction form.

So first we have here two digits after the decimal, so in denominator we will have 100,

`(78)/(100)`

Now we have to convert this into simplest form.

For that we have to find HCF of 78 and 100.

The HCF of 78 and 100 is 2, so we will divide both numerator and denominator by 2,

`(78/2)/(100/2)`

This gives us:

`(39)/(50)`

Answer: The simplest form of 0.78 as as fraction is 39/50.
