So if you need help on this sort of question

-if 1 kg of sugar is $2

How much is 500 g of sugar?-

It's the price of 500 g of sugar you want to find out, right? Well two 500s are 1kg so 2 divided by 2 is 1.

Why am I dividing 2 by 2? Because 1 kg is $2, and two 500s are 1kg (what I struggle with)

And the answer is $1

At least, I think so :p

Another sum.

-If 1 kg of sugar is $4

How much is 250 g of sugar?-

Four 250s are 1kg and 1kg of sugar is $6 so $4 divided by 4 = $1

I haven't learnt how to do hard sums like that yet :(

Maths is sooooooooo hard for me, I know this seems childish but I need help with this
