Write the natural numbers from 2 to 12. What fraction of them are prime numbers

Answer 1

answer:

4. There are 24 hours in a day

We have 8 hours

Hence, required fraction is 8 / 24

= 1/3

5. Since, 1 hour = 60 minutes.

Therefore, the fraction of 40 minutes = 40/60 = 2/3

6.

a)Arya has divided the sandwich into 3 equal parts. So each person will get one part.

b) Each boy receive 1 / 3 part

∴ Required Fraction is 1 / 3

7.

Total number of dresses Kanchan has to dye = 30 dresses

Number of dresses she has finished = 20 dresses

∴ Required Fraction = 20 / 30 = 2 / 3

8.

Natural numbers from 2 to 12 = 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12

Prime number from these = 2, 3, 5, 7, 11

Therefore,

Total numbers = 11

Number of Prime numbers = 5

Fraction = 5/11

9. Natural numbers from 102 to 113 are

102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112, 113

Total number of natural numbers given = 12

Number of prime numbers = 4 [103, 107, 109, 113]

∴ Required Fraction = 4 / 12 = 1 / 3

10.Total number of circles in the figure = 8

Number of circles having X’s in them = 4

∴ Required Fraction = 4 / 8 = 1 / 2

11. Number of CDs Kristin bought from the market = 3

Number of CDs received as gifts = 5

Total number of CDs Kristin have = 3 + 5 = 8

∴ Fraction of CD she bought = 3 / 8

∴ Fraction of CDs received as gifts = 5 / 8

hope it helps :)
