Suppose you only have hundreds tens and ones blocks. what are two different ways you could make the number 1,718

So we are given that we only have ones, tens and hundreds block. There are a lot of possibilities to make 1,718 out of the given blocks. However the two common methods are:

1st method:

Divide 1,718 by 100
1,718 / 100, how many 100s are there in 1,718 = 17 hundreds 
Now we only have 18 left
18 / 10, how many 10s are there in 18 = 1 tens
Now we only have 8 left
8 / 1, how many ones are there in 8 = 8 ones
Therefore 17 hundreds, 1 tens, and 8 ones.

2nd method:

Go directly by tens, skip hundreds

Divide 1,718 by 10
1,718 / 10, how many 10s are there in 1,718 = 171 tens
Now we only have 8 left
8 / 1, how many ones are there in 8 = 8 ones
Therefore 171 tens, and 8 ones.
