# The mass of a crate of mangoes is #11 12/13# kilograms. The mass of a crate of pineapples is #11 11/12# kilograms. Which is heavier?

Crate of mangoes is heavier.

The usual way of comparing fractions is with a common denominator. However, in this case the common denominator is quite big.

There is a much easier way if we realise that both crates weight ALMOST 12 kg. They are both only 1 part away from 12 kg.

We know that the larger the number in the denominator, the smaller is the portion.

The crate of mangoes is therefore closer to 12 kg and heavier than the crate of pineapples.

Both numbers have 11 in them. So as we are just determining which is the greater value we only need to look at the fraction parts.

'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The most straight forward way is to compare numerators (top numbers) after changing the denominators (bottom numbers) to be the same.

Multiplying by 1 does not change the value. However, you can change the way a fraction looks by multiplying by 1 in another form.

Just comparing numerators (top numbers) we observe that case(1) is the greater number.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
