Lucy sang 4 songs. Every song was 5/8 minutes long.

Question

For how much time did she sing in total?
Write your answer in simplest form.
I think that you should do 5/8 x 4. Which equals 2.5.
But if we need it in simplest form, that would be 5/2 or 2 and 1/2. Is that correct?Thanks!

Answer 1

2 1/2 is correct.

Answer 2

thanks!

Answer 3

2.5 or 5/2 or 2 1/2 are all in simplest form

the "mixed fraction" version is probably the least useful form of writing a fraction
even though it seems to be the favourite of many authors.
I don't understand why, since when doing any operation with mixed fractions,
one of the first steps is to change it either into a decimal or an "improper" fraction
e.g. 4 3/5 + 2 1/2
= 23/5 + 5/2
= 46/10 + 25/10 = 71/10 or 7.1

Answer 4

Okay, thanks too!
