Answers
Answer:
2572.678 = 2 thousand + 5 hundred + 7 tens + 2 ones + 6 tenths + 7 hundredths + 8 thousandths
= 2000 + 500 + 70 + 2 + 6/10 + 7/100 + 8/1000 -->(Fractional expansion)
2000 + 500 + 70 + 2 + 0.6 + 0.07 + 0.08 -->Decimal expansion
Write in expanded form :
1) 125.84
Solution :
125.84 = 1 hundred + 2 tens + 5 ones + 8 tenths + 4 hundredths
= 100 + 20 + 5 + 8/10 + 4/100
2) 0.485
Solution :
0.485 = 0 ones + 4 tenths + 8 hundredths + 5 thousandths
= 0 + 4/10 + 8/100 + 5/1000
= 4/10 + 8/100 + 5/1000
3) 9.9
Solution :
9.9 = 9 ones + 9 tenths
= 9 + 9/10
Expanded form to decimal form :
1)Check the places of the given number in whole part.
2)Write that in expanded form.
3) Check the place values of fractional part and then write them after decimal point.
Example :
200 + 50 + 9 + 1/10 + 3/100 + 6/1000
2 = hundred place
5 = tens place
9 = ones place
1 = tenths place
3 = hundredths place
6 = thousandths place
