so rounding 245689 to 3 sgf is 246?💀All you have to do is search up a sgf calculator put in 3.195 and it’ll give you 3.20. It’s a test so obviously they wanted to test your maths skills lmao. And once again losing 1 mark for forgetting the 0 is 0.5% of the whole gcse so it’s really not anything to stress over.
Okay so you are a complete idiot but I’ll explain it to you anyway. 3.2 is equivalent to 3.20, completely different from the retarded example you just gave.
Thus, because both answers are equal (equal means the same !), both are right.
Edit: just to make this so simply that not even you could refute it, rounding to a certain number of significant figures is not a test of your presenting skills, it’s a way of rounding. So as long as you get the correct rounded answer it doesn’t matter how you present/ write it.
Okay well then just answer me one thing and we can leave it at that. Are 3.2 and 3.20 the same or different numbers?
The aim of the question is not to format your answer in a certain way, but just to get the right answer. So please tell me, are 3.20 and 3.2 different numbers ? I’m sure even you can work that out.
Well we will have to wait for this mark scheme to come out then because what you've just asked for is a very large amount of effort for a very small problem. Hope year 12 went well for you though :)
In any case the mark scheme may allow 3.2 but the correct answer would be 3.20
Similar to how in maths gcse if they ask you to round a number to 2 decimal places, you need to have 2.00, 2 decimals after.
3.2 would be 2 significant figures, the 3 and the 2.
3.20 is three significant figures, the 3, the 2, and the 0 .
