Question

Round the decimal in the figure to its nearest tenths.

  1. 0.1
  2. 0.2
  3. 0.3
  4. 0.4

Hint:

We have to find the decimal number showed in the figure and then round off it to nearest tenth. At first we will start with finding the decimal number formed in figure, considering all boxes together to be a whole 1, then we can see that only 44 boxes is colored so the number formed will be 0.44. Further we will round off the tenth place which is first digit on right of decimal point as the number after 4 is 4 so the 4 will remain as 4.

The correct answer is: 0.4


decimal number formed= 0.44
decimal number rounded off to nearest tenth = 0.4

The pair of fractions among the following that are not equivalent is

a. 2 over 3 and 12 over 18
2cross times18           12cross times3
= 36                = 36
As the cross multiplication of both fractions are equal. So its an equivalent fraction.
b. 4 over 5 and 40 over 50
4cross times 50           40 cross times 5
= 200             = 200
As the cross multiplication of both fraction are equal. So its an equivalent fraction.
c. 1 half space a n d space 2 over 3
1 cross times 3          2 cross times 2
= 3              = 4
as the cross multiplication of both fractions are not equal. So its not an equivalent fraction.
d. 7 over 6 space a n d 14 over 12
7 cross times 12       14cross times 6

as the cross multiplication of both fractions are equal. So its an equivalent fraction.
Therefore the pair of fraction which is not an equivalent fraction is fraction numerator 1 over denominator 2 space end fraction space a n d space 2 over 3.

If a game of chance consists of spinning an arrow which is equally likely to come to rest pointing to one of the number 1,2,3……12 , then the probability that it will point to an odd number is:

Total number of outcome = 12
No. possible outcome(no. odd nos. from 1 to 12 ) = 6
Probability =6 over 12 equals 1 half
So, the probability of getting the odd number is 1 half.

A bag contains 5 red balls and some blue balls. If the probability of drawing a blue ball is double that of a red ball, then the number of blue balls in a bag is:

Let the probability of getting balls be x.
Then the probability of getting blue ball = 2x
As we know the sum of probability of all the possible outcomes is 1.
So, 2x + x  = 1
rightwards double arrow 3 x space space equals 1
rightwards double arrow x space space space space equals 1 third
Let total number of probability be P.
The probability of getting red balls =5 over P
but as derived probability of getting red ball = x =1 third
