ii) 8.88
iii) 0.91
iv) 0.50
v) 3.03
vi) 6.74
Answer:
i) The underlined digit is in ones place. So its place value is 4 x 1 = 4
ii) The underlined digit is in hundredths place. So its place value is \(\frac{8}{100}\)
iii) The underlined digit is in tenths place. So its place value is \(\frac{9}{10}\).
iv) The underlined digit is in tenths place. So its place value is \(\frac{5}{10}\).
v) The underlined digit is in hundredths place. So its place value is \(\frac{3}{100}\).
vi) The underlined digit is in tenths place. So its place value is \(\frac{7}{10}\).
Question 5.
Find greater in the following.
(i) 0 0.2 (or) 0.4
(ii) 70.08 (or) 70.7
(iii) 6.6 (or) 6.58
(iv) 7.4 (or) 7.35
(v) 0.76 (or) 0.8
Answer:
(i) 0.2 or 0.4 2
0.2 = \(\frac{2}{10}\) and 0.4 = \(\frac{4}{10}\)
\(\frac{2}{10}\) means 2 parts out of 10 parts.
\(\frac{4}{10}\) means 4 parts out of 10 parts.
∴ 4 > 2
(i.e) 0.4 > 0.2
(ii) 70.08 (or) 70.7
Whole part of both is 70.
0.08 = \(\frac{8}{100}\); 0.7 = \(\frac{7}{10}=\frac{7 \times 10}{10 \times 10}=\frac{70}{100}\)
0.08 means 8 parts out of 100 parts
0.7 means 70 parts out of 100 parts
∴ 70 > 8
(i.e.,) 70.7 > 70.08
(iii) 6.6 or 6.58
Whole part of both is 6.
0.6 = \(\frac{6}{10}=\frac{6 \times 10}{10 \times 10}=\frac{60}{100}\); 0.58 = \(\frac{58}{100}\)
0.6 means 60 parts out of 100 parts.
0.58 means 58 parts out of 100 parts.
∴ 60 > 58
(i.e.,) 6.6 > 6.58
(iv) 7.4 or 7.35
Whole part of both is 7.
0.4 = \(\frac{4}{10}=\frac{4 \times 10}{10 \times 10}=\frac{40}{100}\); 0.35 = \(\frac{35}{100}\)
0.4 means 40 parts out of 100 parts.
0.35 means 35 parts out of 100 parts.
∴ 40 > 35
(i.e.,) 7.4 > 7.35
(v) 0.76 or 0.8
Whole part of both is zero.
0.76 = \(\frac{76}{100}\); 0.8 = \(\frac{8}{10}=\frac{8 \times 10}{10 \times 10}=\frac{80}{100}\)
0.76 means 76 parts out of 100 parts.
0.8 means 80 parts out of 100 parts.
∴ 80 > 76
(i.e.,) 0.8 > 0.76
Question 6.
Rewrite in ascending order.
i) 0.04, 1.04, 0.14, 1.14
ii) 9.09, 0.99, 1.1, 7
Answer:
i) 0.04,1.04,0.14,1.14
By observation, we can say that
0.04 < 0.14 < 1.04 < 1.14 (ascending order)
ii) 9.09, 0.99, 1.1, 7
By observation, we can say that
0.99 < 1.1 < 7 < 9.09 (ascending order)
Question 7.
Rewrite in descending order
i) 8.6, 8.59, 8.09, 8.8
ii) 6.8, 8.66, 8.06, 8.68
Answer:
i) 8.6,8.59,8.09, 8.8
By observation, we can say that
8.8 > 8.6 > 8.59 > 8.09 (descending order)
ii) 6.8, 8.66, 8.06, 8.68
By observation, we can say that
8.68 > 8.66 > 8.06 > 6.8 (descending order)
