For Example I'll use 7.967

7 falls into the ones

.

9 falls into the 10ths

6 into 100ths

7 into 1000ths

Soo you write it like so

7x1 + 9x1/10 + 6x1/100 + 7x1/1000

7 falls into the ones

.

9 falls into the 10ths

6 into 100ths

7 into 1000ths

Soo you write it like so

7x1 + 9x1/10 + 6x1/100 + 7x1/1000
