When we want to put things in order, we use ordinal numbers so we can tell the position of that thing.
For example, if there is a road with three houses, you will pass them in order of the first house, the second and the third.
In the following sentences, spell the ordinal number in full to complete the sentence. e.g. first, twenty-ninth, seventieth (not 1st, 29th, 70th).
