Answer: 700.012
Step-by-step explanation:
1) You must learn and practice the place names and place values as much for whole numbers as for decimal numbers:
i) Whole numbers:
Millions - 1,000,000
Hundred thousands - 100,000
Ten thousands - 10,000
Thousands - 1,000
Hundreds - 100
Tens - 10
Ones - 1
ii) Decimals
Tenths - 1 / 10 = 0.1
Hundredths - 1/ 100 = 0.01
Thousandths - 1 / 1,000 = 0.001
Ten thounsandths - 1 / 10,000 = 0.0001
2) Seven hundred = 7 × 100 = 700
3) Twelve thousandths = 12 / 1,000 = 0.012
4) Seven hundred and twelve thousandths = 700 + 0.012 = 700.012
