Tks Eva!

Between 511 to 519, tenths place is 1, so it is 51something. Then the value of the digit is 4. So answer is 514.

514.1 I just taught this in school today :b

What does it means the value of the digit 4 is 4?

It means it is in the ones place

if the term tenth is used, then the answer should be a decimal. do not confuse tens with tenths.

It's a P4 qn. So no decimal yet, I think.

It's a decimal topic btw..

Thanks Charlotte. I would probably fail my maths if I take the exam now. 😅

Answer is 514

514.1

514.1

Thank you all!😊

514

Thanks Adrian but still can't see why the shaded part is = z + y + red triangle. Sorry I'm a bit slow ! 😔

∆ ACT = ∆ ABT. Agree?

Yes equal

∆ shaded in [x] on the left = ∆ shaded in [x] on the right. Agree?

Yes agree, x on the left = x on the right

Now, the 2 red ∆ are equal. Agree?

Ah ic yes. Then y = shaded y !! Yay.. I see now. Great.. Thanks for your patience in teaching !!

Me? Thank you! 😄

Thanks
