Solution:
(c) Converting the given decimals to like decimals, we have 0.070 and 0.008.

Note: Decimals having the same number of digits on the right of the decimal point are known as like decimals.

1/8 as a decimal? 1 0.125. 2 0.225. 3 0.325. 4 0.425.

Question 16:
Which of the following decimals is the greatest?
(a) 0.182 (b) 0.0925 (c) 0.29 (d) 0.038
Solution:
(c) Here, whole part of all numbers are same and tenths part of 0.0925 and 0.038 are same
i.e. 0 and tenths part of 0.182 =1/10
and tenths part of 0.29 = 2/10
Hence, 0.29 is the greatest.

Now, we will compare the tenths part of 0.27, 0.082 and 0.103.
Tenths part of 0.27 = 2/10
Tenths part of 0.082 = 0/10
and tenths part of 0.103 =1/10
Clearly, tenths part of 0.082 is smallest.
Hence, 0.082 is the smallest decimal.

Question 18:
13.572 correct to the tenths place is ,
(a) 10 (b) 13.57 (c) 14.5 (d) 13.6
Solution:
(d) For rounding off to tenths place, we look at the hundredths place.
Here, the digit at hundredths place is 7 which is greater than 5. So, the digit at the tenths place (5) will be increased by 1 and digits at the hundredths and thousandths place will be written as equal to zero.
Hence, rounding off 13.572 to nearest tenths, we get 13.6.

What is formal notation for rounding to the nearest hundredth (notation, math)?.

Question 124:
Match the fractions of Column I with the shaded or marked portion of figures of Column II

Solution:
On observing the figures given in Column II, we get
(a) Line is divided into 10 equal parts out of which 6 parts are shaded.
The fraction of shaded portion to the total parts = 6/10
(b) Square is divided into 16 equal parts out of which 6 parts are shaded.
The fraction of shaded portion to the total parts = 6/16
(c) Rectangle is divided into 7 equal parts out of which 6 parts are shaded.
The fraction of shaded portion to the total parts = 6/7
(d) Each of the two circle is divided in 4 equal parts out of which 4 parts of one circle and 2 parts of second circle are shaded.
The fraction of shaded portion to the total parts = 4+2 / 4+4 = 6/8
(e) Rectangle is divided into 6 equal parts out of which 6 are shaded.
The fraction of shaded portion to the total parts =
Hence, the (i) ->d, (ii) -> a, (iii) ->e, (iv) -> b, (v) -> c

Question 125:
Find the fraction that represents the number of natural numbers to total numbers in the collection 0,1, 2, 3, 4, 5. What fraction will it be for whole number?
Solution:
Given collection is 0, 1, 2, 3, 4, 5.
Natural numbers = 1, 2, 3, 4, 5
The fraction of natural numbers to the collection =5/6
Now, whole numbers = 0,1,2, 3, 4, 5, 6
The fraction of whole numbers to the collection = 6/6 = 1/1

Question 126:
Write the fraction representing the total number of natural numbers in the collection of numbers -3, -2,-1, 0,1, 2, 3. What fraction will it be for whole numbers? What fraction will it be for integers?
Solution:
Given collection is -3 -2,-1, 0,1,2, 3.
Natural numbers = 1,2, 3
The fraction of natural numbers to the collection = 3/7
Now, whole numbers = 0,1,2,3
The fraction of whole numbers to the collection = 4/7
and integers = – 3, -2, -1, 0,1,2, 3
The fraction of integers to the collection 7/7 = 1/1

Question 127:
Write a pair of fractions whose sum is 7/11 and difference is 2/11.
Solution:
