1. Answer :
Tenths place is nothing but the position of first digit after the decimal point.
In 0.5276, the first digit after the decimal point is 5.
So, the digit in the tenths place is 5.
2. Answer :
Hundredths place is nothing but the position of second digit after the decimal point.
In 1.2347, the second digit after the decimal point is 3.
So, the digit in the hundredths place is 3.
3. Answer :
Hundreds place is nothing but the position of second digit before the decimal point.
In 5678.92, the second digit before the decimal point is 7.
So, the digit in the hundreds place is 7.
4. Answer :
Thousandths place is nothing but the position of third digit after the decimal point.
In 9856.9202, the third digit after the decimal point is 0.
So, the digit in the thousandths place is 0.
5. Answer :
In 207.159, '9' is the third digit after the decimal point.
According to the decimal place value chart, 9 is at thousandths place.
So, 9 is at thousandths place.
6. Answer :
In 12.0598, '5' is the second digit after the decimal point.
According to the decimal place value chart, 5 is at hundredths place.
So, 5 is at hundredths place.
7. Answer :
In 58702.19, '7' is the third digit before the decimal point.
According to the decimal place value chart, 7 is at hundreds place.
So, 7 is at hundreds place.
8. Answer :
In 0.0048, '4' is the third digit after the decimal point.
According to the decimal place value chart, 4 is at thousandths place.
So, 4 is at thousandths place.
9. Answer :
Ten thousands place is nothing but the position of fifth digit before the decimal point.
In 13256.02, the fifth digit after the decimal point is 1.
So, the digit in the thousands place is 1.
10. Answer :
Here we don't have decimal point. So we can assume that the decimal point is at the end.
That is 7800202 = 7800202 .
Thousands place is nothing but the position of fourth digit before the decimal point.
In 7800202, the fourth digit before the decimal point is 0.
So, the digit in the thousands place is 0.
11. Answer :
"forty-five and six tenths"
From the given verbal phrase, we can have the numbers and their positions as given below.
4 - tens
5 - ones
6 - tenths
So, we have
"forty-five and six tenths" = 45.6
12. Answer :
"sixty-five, five-tenths and seven-hundredths"
From the given verbal phrase, we can have the numbers and their positions as given below.
6 - tens
5 - ones
5 - tenths
7 - hundredths
So, we have
"sixty-five, five-tenths and seven-hundredths" = 65.57
13. Answer :
"seventy-four and eight-thousandths"
7 - tens
4 - ones
0 - tenths
0 - hundredths
8 - thousandths
So, we have
"seventy-four and eight-thousandths" = 74.008
14. Answer :
0.36 x 0.24 = 0.0864
Whenever we want to round the number to the nearest hundredths, first we have to look at the digit at thousandths place. If it is greater than or equal to 5, we have to add 1 to the digit at hundredths place.
Here, the digit at the thousandths place is 6 which is greater than 5.
So we have to add 1 to the digit at the hundredths place.
So, we have
0.0864 ≈ 0.09
15. Answer :
5/1.2 = 50/12
5/1.2 = 4.166666...........
Whenever we want to round the number to the nearest thousandths, first we have to look at the digit at ten thousandths place. If it is greater than or equal to 5, we have to add 1 to the digit at thousandths place.
Here, the digit at the ten thousandths place is 6 which is greater than 5.
So we have to add 1 to the digit at the thousandths place.
So, we have
4.16666....... ≈ 4.167
