What is 168.023 in expanded form using fractions
bonufazy [111]

Answer:

The expanded form of 168.023 is 100 + 60 + 8 + \frac{2}{100} + \frac{3}{1000}

Step-by-step explanation:

Expanded form:

  • Is a way to write numbers to see the math value of the digits.
  • When numbers are separated into their place values and decimal places they can also form a mathematical expression.
  • Ex: 5,325.27 in expanded form is 5,000 + 300 + 20 + 5 + \frac{2}{10} + \frac{7}{100} = 5,325.27

Let us solve the question

∵ The number is 168.023

∵ Its hundreds digit is 1

∴ Its value = 100

∵ Its tens digit is 6

∴ Its value = 60

∵ Its units digit is 8

∴ Its value = 8

∵ Its tenths digit is 0

∴ Its value = 0

∵ Its hundredths digit is 2

∴ Its value = \frac{2}{100}

∵ Its thousandths digit is 3

∴ Its value = \frac{3}{1000}

∴ The expanded form of 168.023 = 100 + 60 + 8 + \frac{2}{100} + \frac{3}{1000}
