Hi,

I need to get it done for half an hour / a day/ a month.

I know that 30 minutes = half an hour.

Q1

half an hour = a half hour = one second hour ? I think “a half =one second”.

90 minutes = one and a half hours = one and one second hours.

= one and half an hour = one hour and thirty minutes

= one point five hours?

Which are more spoken?
We never say one and one second hours.
We say
eg an hour and a half <<<<<

one and a half hours <<<<<

eg one point five hours

Q2

1/2 = ~~one second~~ = a half = one half

1/4 = one fourth = a quarter = one quarter

One and a quarter hours ~~= one and one fourth hours~~ = one hour and twenty minutes?

Which are more spoken?
We say
eg an hour and a quarter
eg an hour and twenty inutes

Try to write a few sentences, and I'll check them for you.

q1

I am confused about

1/4 = one fourth

Why 1/2 can not write as one second ?

Talking about math of fraction. I have learned them as below , help me check

1/2 = one second

1/3= one third , 2/3 = two thirds

1/4= one fourth, 3/4= three fourths

1/7 = one seventh, 5/7 = five sevenths

62/ 100 = sixty-two/ hundredths

q2

an hour and a half = one hour and a half , right?

an and one can change each other ?

Thanks again

Why 1/2 can not write as one second ?-- Because we don't, that's all.

Talking about math of fraction. I have learned them as below , help me check
1/2 = one half. The rest are OK.

an hour and a half = one hour and a half , right?-- Right.

an and one can change each other ?-- Yes, but 'one' used when being more precise.

Hi,

1/4= one fourth, No, one/a quarter
3/4= three fourths No, three quarters

Clive

Jacky56Lin · Answer

I got it.

So How can I say ?

3/2 = three seconds or three halves

Mister Micawber · Answer

3/2 = three halves
5/4 = five fourths or five quarters

I have to disagree with Clive (if I understand his post correctly): one-fourth is as good as one quarter any day.

Hi,

It would sound rather odd where I live.

Jacky56Lin · Answer

q3

1 1/2 = one and a half = one and one half

3 5/2 = three and five halves

2 1/4 = two and a/one quarter = two and one fourth

q4

I work for a half day/ month /year = I work for half a day/ month /year ?

q5

I work for one and a half hours.

I work for an/one hour and a half.

I work for one and half an hour. correct??

I work for one and a half days/ months/ years .

I work for a/one day/ month / year and a half .

I work for two and a half days/ months/ years .

I work for two days/ months / years and a half .

Teachers ! help me check above.

Thanks again.

Mister Micawber · Answer

You can use all these, Jacky (I deleted only one):

1 1/2 = one and a half = one and one half
3 5/2 = three and five halves
2 1/4 = two and a/one quarter = two and one fourth

I worked for a half hour. = I worked for half an hour
I worked for a half day/ month /year = I work for half a day/ month /year

I worked for one and a half hours.
I worked for an/one hour and a half.

I worked for one and a half days/ months/ years .
I worked for a/ day/ month / year and a half .-- Be consistent: one day and one half (precise) or a day and a half (more casual)

I worked for two and a half days/ months/ years .
I worked for two days/ months / years and a half .
