Guys I need help with this, I do not understand this..

Sometimes it says shade 0.X of a shape.

Now I did a practice paper and one question was there are 10 squares it says shade 0.7 of this shape? What do I do?

Second it says

Apples cost £2 per KG
Oranges £0.34 each
Bananas £2.40 per KG

1 KG of apples

2 oranges

3 kg bananas
-
4

I don't know how many Bananas the person buys how I work that out?

Thanks !

0.7 = 7/10 so you shade in 7/10 of the 10 squares

The question doesn't ask how many bananas are bought so you needn't work it out. You are given quantities and the price per quantity - it's addition.

OT: how long has Ackbeet been green?!

No it 3/4 kg Bannans, it gives it as a fraction.

Second what about if the shape does not have 10 squares, what if it has 15, I need to know the method please..

Thanks

If 1kg of bananas is £2.40 how much will 0.75kg (which is 3/4 of 1kg) cost?
