Help DH and me solve this silly maths argument

[ADayGivingMeHope]

Ok it's not an AIBU but we need this argument settled!!

I am 30.

I just said to my DH that I am MORE than half his age...
We are talking about someone on TV who is 70
DH says I am LESS than half his age.

Half his age is 35. I am 40 years younger than him so surely I am MORE than half his age?

DH says half his age is 35 and I am 30 so I'm less than half his age...

Tell us who is right please!

DH is correct

if you ate more than half of a cake, you'd have eaten over 50% of it

if you are more than half of someone's age, you're over 50% of their age

The difference between your age (30) and the man's age (70) is 40 years.

Just because 40 years is the difference, it doesn't mean you're more than half his age.

You're calculating 2 different things and that's why you're wrong!

Another way of putting it, at 30 years old, you are 40 years younger than the man.

Or, if you're 30, and someone is 40 years older than you, how old would they be? Answer = 70.

Your DH is correct, and my 8 year old could tell you you're wrong if that would help?

I'm crap at maths, but even I don't struggle with this, sorry

Okay. I get you.

But this isn't a maths problem, it's a case of customary implication.

When we talk about or compare people's ages, we always count forwards from when they were born. So your DH (and every other British English speaker on the planet) goes "0 to 35, which equals 35 and 30 is less than 35, so Day is less than half his age" whereas you're counting backwards from his age now and thinking "70 minus 35 which equals 35, so to get back to my age, you have to go more than halfway, therefore I'm more than half his age".

Express it as fractions, makes it easier...

35/70 is a half
30/70 is three sevenths,

Three sevenths is less than a half therefore:

You are less than "half his age"

You're thinking 'more' in the sense of 'a greater proportion'. Your dh is thinking 'less' in the sense of 'numerically lower'. Most people (me too) would use these terms in the same way as your dh.

taracarter that's what I meant, counting backwards from his age, so more than half his age.

I don't think it's even a phrasing thing, because more than and less than mean the same in English as they do in maths! Therefore, it must be a wine thing.
Your DH is totally right, no question about it. As a 30 year old, you are less than half the age of a 70 year old. And the 70 year old is more than twice your age, because twice your age is 60.

Do you really still not get it op?

How much wine have had exactly?

35 is half of 70.

If you're over 35, then you're more than half of a 70 year old's age.

Because 36 is more than half of 70.

You're 30. You're not even half of a 70 year old's age.

Do you manage to hold down a job and/or raise children?!

I'm with your DH too, and I can't understand your logic!

Dh is right.

🤗 ok, ok. It must be a wine thing 🤣

I think I have to feed my husband more than half the pizza we have cooking to shut his smug face up now 🤣 🙈

Half his age is 35.

You're less than that.

So how can you be more than half his age?

Are you voting on Thursday?

😏

By your logic OP, someone who is 2 is more than half his age?!

Oh dear.

I see where the confusion is coming from as in 40 yrs younger is more than half his age span but thats not how we generally talk about it we would say at 30 you are less than half the age of the 70 yr old (because you are!)

I think you are confusing this with when shops have a sale and they say "better than half-price" or "more than half off", where the new price is less than half of the original price, but that's because the reduction is more than half.

Your dh is right

Seriously? Half his age is 35. You are 30. You therefore cannot be anything but less than half his age.

Anything else is stupidity or witchcraft and there madness lies.

Think of it like this:

He is 70. So half his age is 35. 35 is therefore the answer/equivalent to "half his age".

So if you remove the "half his age" in the sentence and replace it with the answer/equivalent which is 35, you would be saying:

"I am more than 35". You're not, you're less than 35!

So DH is tight, you're less than half his age.

Quite confusing way of trying to explain this, I admit, but maybe it might make sense in a wine induced fug?
