Solution:
\(\frac{45,9}{81,9}=\frac{5}{9}\) (d)
(Dividing numerator and denominator by 9)

Solution:
\(\frac{9}{15}\) is not equal to \(\frac{4}{5}\). (b)
∴ \(\frac{9}{15}=\frac{3}{5}\)
Question 9.

Solution:
The lowest form of this can be written as
\(\frac{39}{87}=\frac{13}{29}\)
Question 10.
A pair of like fraction is
Solution:
\(\frac{3}{7}, \frac{16}{7}\)
Like fractions are those fractions who have same denominator. (b)
Question 11.
Which of the following fractions is the greatest?
Solution:
\(\frac{5}{6}\) (a)
Question 12.
Which of the following fractions is the smallest?
Solution:
\(\frac{11}{10}\) (c)
Question 13.
Which of the following is a false statement?
Solution:
\(\frac{3}{4}=\frac{6}{16}\)
Because, if we multiply and divide the fraction with 4, we get

Higher Order Thinking Skills (Hots)
Question 1.
Write all proper fractions whose sum of numerator and denominator is 12.
Solution:
⇒ 1 + 11 = 12
⇒ 2 + 10 = 12
⇒ 3 + 9 = 12
⇒ 4 + 8 = 12
⇒ 5 + 7=12
Question 2.
The given figure represents the preferences of the students during breakfast in a hostel mess. If the total number of students in the mess is 540, then with reference to the given figure, answer the following questions:
(i) What is the number of students who prefer coffee?
(ii) Whose number is greater, milk drinkers or orange juice drinkers and by what number?
(iii) What is the total number of students who drink mango shake or coffee? Is it equal to milk drinker?
(iv) Is the sum of all fractions in the given figure equal to 1 ?
Solution:
(i) Total number of students = 540
Ratio of students who prefer coffee = \(\frac{1}{6}\)
∴ Number of student prefer coffee
∴ Milk drinkers are more than orange drinkers by number = 45.
(iii) Number of Mango shake drinkers
\(=540 \times \frac{1}{6}=90\)
Number of coffee drinkers
\(=540 \times \frac{1}{6}=90\)
Total number of mango shake and coffee drinkers = 90 + 90 = 180
Milk drinkers = 180
Yes, it is equal to milk drinkers.
(iv) Sum of all fraction are:
Yes, the sum of all the fractions are equal to 1.
