Welcome to Math Help Forum!If the capacity is given to the nearest litre, then this means that the true capacity lies anywhere between litres and litres. The maximum error is therefore litre.

I'm not certain how the degree of accuracy is to be expressed, but a percentage would be quite a sensible way. So we need first to express the maximum error as a percentage of the stated capacity - that's

%and then subtract this from % to give the degree of accuracy. . So the figure is % accurate.

%, correct to 2 d.p.
