Question

Convert the fraction 7 over 8 into decimal.

  1. 0.775
  2. 0.625
  3. 0.875
  4. 0.95

Hint:

To convert any fraction into decimal number we have to divide numerator from denominator. When numerator is less than denominator we have to first write a decimal in quotient which gives a 0 in the right hand side of the dividend after which we can start dividing now every time when we will get some number as remainder we will write 0 at the right and divide as usual until the remainder becomes 0. During division we will write the quotient in the right hand side of the decimal.

The correct answer is: 0.875


Decimal form of 7 over 8= 0.875
long division by 8 yields 0.875 pile none 70 negative 64 none _ _ _ _ none none 60 none negative 56 none none _ _ _ _ none none none 40 none none negative 40 none none none _ _ _ _ _ none none none 00 end pile end long division

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.
