Question

Write 1.64 as a mixed number in lowest terms.

Answer 1

1 16/25

Explanation:

You write 1.64 as 1 64/100

Then you simplify it to 1 16/25

Answer 2

`1(16)/(25)`

Explanation:

So we have the decimal:

`1.64`

We can rewrite this as:

`=1+0.64`

0.64 is the same as 64/100. So:

`=1+(64)/(100)`

We can divide both layers by 4. This gives us:

`=1+(64/4)/(100/4)`

Divide:

`=1+(16)/(25)`

So, as a mixed fraction, this is:

`1(16)/(25)`

And we're done!
