How to interpret the recharge time?

For whatever reason they choose to use fractions instead of decimals, but 1/4 is 0.25, 1/2 is 0.5 and 3/4 is 0.75

I can't remember if any other fractions come up, but you should be able to work them out or find conversions online if they do.

Many thanks.

It is really strange that they decided to inform the recharge in this way lol.

A fraction takes two integers and places them in a ratio (like 3/4 or 10/15). A decimal can express the same numerical quantity, but it does so with a single number (like 0.75 or 0.66). So, the fraction makes the relationship among numbers clear in the way it is written, while the decimal does not.

A study asked people to identify the specific relationship shown in a display and found that people were equally good at using fractions and decimals for continuous displays, but much better at using fractions than decimals for discrete and discretized displays.

The number 7π is not the same number as ANY number written with a decimal representation having finitely many digits. So if you want to write numbers exactly, decimals are rarely useful.

In fact, it turns out that almost every real number does not have a decimal representation with finitely many digits — what I’ll call a “nice” decimal representation. No irrational numbers have a “nice” representation.

So when you encounter a rational number in a math class, it is common to see it written as a fraction and not as a decimal because decimals aren’t sufficient to represent most rational numbers in a “nice” way.

While it is true 1/2=0.5 and 3/8=0.375 exactly it is not true that 1/6=0.16667 . The last equation is approximate but not exact.Fractions are very simple things. The fraction a/b means that you take the number 1 , divide it into b equal pieces and take a such pieces. Decimals, however, don’t offer you that kind of flexibility. They only let you divide things into multiples of ten (as opposed to fractions which let you divide into any number of parts).
