The unknown number is 124.1.

Step-by-step explanation:

Let the unknown number be x.

We know that

1 hundreds = 100 ones

1 tens = 10 ones

1 tenth = 0.1 ones

It is given that the number has 1 hundreds, 4 ones, 2 tens, and 1 tenths.

x = 1 hundreds + 2 tens + 4 ones + 1 tenths.

Using the above conversions we get

Therefore the unknown number is 124.1.
