Question 1:
Which of the following fraction is arranged in ascending order of their value?
a) \(\frac{1}{4} \) , \(\frac{2}{7} \) , \(\frac{3}{4} \) , \(\frac{4}{7} \) , \(\frac{5}{7} \) , \(\frac{6}{5} \)
b) \(\frac{1}{4} \) ,\(\frac{2}{7} \) ,\(\frac{4}{7} \) ,\(\frac{5}{7} \) ,\(\frac{3}{4} \) ,\(\frac{6}{5} \)
c) \(\frac{2}{7} \) ,\(\frac{1}{4} \) ,\(\frac{4}{7} \) ,\(\frac{3}{4} \) ,\(\frac{5}{7} \) ,\(\frac{6}{5} \)
d) \(\frac{2}{7} \) ,\(\frac{1}{4} \) ,\(\frac{4}{7} \) ,\(\frac{5}{7} \) ,\(\frac{3}{4} \) ,\(\frac{6}{5} \)
Answer : b) \(\frac{1}{4} \) ,\(\frac{2}{7} \) ,\(\frac{4}{7} \) ,\(\frac{5}{7} \) ,\(\frac{3}{4} \) ,\(\frac{6}{5} \)
Solution :
Converting the given fractions into decimal numbers, we have
\(\frac{1}{4} \) = 0.25
\(\frac{2}{7} \) = 0.28
\(\frac{3}{4} \) = 0.75
\(\frac{4}{7} \) = 0.57
\(\frac{5}{7} \) = 0.71
\(\frac{6}{5} \) = 1.2
So, 0.25 < 0.28 < 0.57 < 0.71 < 0.75 < 1.2
Corresponding fraction is \(\frac{1}{4} \) < \(\frac{2}{7} \) < \(\frac{4}{7} \) < \(\frac{5}{7} \) < \(\frac{3}{4} \) < \(\frac{6}{5} \)
Hence the answer is option b.
Question 2:
Which of the following fraction is the largest?
a) \(\frac{8}{9} \)
b) \(\frac{18}{23} \)
c) \(\frac{16}{21} \)
d) \(\frac{14}{17} \)
Answer : a) \(\frac{8}{9} \)
Solution :
Converting the given fractions into decimal form, we have,
\(\frac{8}{9} \) = 0.88
\(\frac{18}{23} \) = 0.78
\(\frac{16}{21} \) = 0.76
\(\frac{14}{17} \) = 0.82
From the above, 0.88 is the largest.
Corresponding fraction is \(\frac{8}{9} \) .
Question 3:
Which of the following fraction is greater than \(\frac{4}{5} \) and less than \(\frac{6}{7} \) ?
a) \(\frac{2}{3} \)
b) \(\frac{3}{4} \)
c) \(\frac{5}{6} \)
d) \(\frac{10}{11} \)
Answer : c)\(\frac{5}{6} \)
Solution :
We have to find X such that \(\frac{4}{5} \) < X < \(\frac{6}{7} \)
Converting each fraction into decimal form, we get:
\(\frac{4}{5} \) = 0.8
\(\frac{6}{7} \) = 0.85
We have to find the fraction which is greater than 0.8and less than 0.85.
Now,
\(\frac{2}{3} \) = 0.66
\(\frac{3}{4} \) = 0.75
\(\frac{5}{6} \) = 0.83
\(\frac{10}{11} \) = 0.91
Clearly, 0.83 lies between 0.8 and 0.85.
Required fraction is \(\frac{5}{6} \)
Question 4:
Which of the following fraction does not lie between \(\frac{5}{6} \) and \(\frac{8}{15} \) ?
a)\(\frac{2}{3} \)
b)\(\frac{3}{4} \)
c)\(\frac{4}{5} \)
d)\(\frac{6}{7} \)
Answer : d) \(\frac{6}{7} \)
Solution :
Converting each of the given fractions into decimal form, we get,
\(\frac{5}{6} \) = 0.83
\(\frac{8}{15} \) = 0.53
\(\frac{2}{3} \) = 0.66
\(\frac{3}{4} \) = 0.75
\(\frac{4}{5} \) = 0.8
\(\frac{6}{7} \) = 0.85
Clearly, 0.85 does not lie between 0.83 and 0.53
Hence the required fraction is\(\frac{6}{7} \) .
Question 5: Which of the following is larger than 3/5?
