Question 1.
 Write a decimal number sentence to identify the total value of the place value disks.
 
Answer:
 a.20.53.
Explanation:
 In the above-given question,
 given that,
 2 tens + 5 tenths + 3 hundredths.
 2 tens = 20.
 5 tenths = 5/10.
 5/10 = 0.5.
 3 hundredths = 3/100.
 3/100 = 0.03.
 20 + 0.5 + 0.03 = 20.53.
Answer:
 b.20.53.
Explanation:
 In the above-given question,
 given that,
 5 hundred + 4 hundredths.
 5 hundred = 500.
 4 hundredths = 4/100.
 4/100 = 0.04.
 500 + 0.04 = 500.04.
