Question 1:

Write the fractions. Are all these fractions equivalent?
(a)
(b)

Answer:

(a) In the given circles, 1 out of 2, 2 out of 4, 3 out of 6,
and 4 out of 8 equal parts are shaded respectively. Therefore, these circles represent

Also, all these fractions are equivalent.
(b)
In the given rectangles, 4 out of 12, 3 out of 9, 2 out of 6, 1 out of 3, and 6 out of 15 equal parts (i.e., circles) are shaded respectively. Therefore, these rectangles represent

No, not all of these fractions are equivalent.




Question 2:

Write the fractions and pair up the equivalent fractions from each row.

Answer:

(a) Here, 1 part is shaded out of 2 equal parts (i.e., rectangle). Hence, this
figure represents a fraction.
(b) Here, 4 parts are shaded out of 6 equal parts (i.e., rectangle). Hence,
this figure represents a fraction
(c) Here, 3 parts are shaded out of 9 equal parts (i.e., squares). Hence, this
figure represents a fraction 
(d) Here, 2 parts are shaded out of 8 equal parts (i.e., rectangle). Hence,
this figure represents a fraction 
(e) Here, 3 parts are shaded out of 4 equal parts (i.e., squares). Hence, this
figure represents a fraction .
(i) Here, 6 parts are shaded out of 18 equal parts (i.e., triangles). Hence, this figure represents a fraction 
(ii) Here, 4 parts are shaded out of 8 equal parts (i.e., rectangles). Hence, this figure represents a fraction 
(iii) Here, 12 parts are shaded out of 16 equal parts (i.e., squares). Hence, this figure represents a fraction 
(iv) Here, 8 parts are shaded out of 12 equal parts (i.e., rectangles). Hence, this figure represents a fraction 
(v) Here, 4 parts are shaded out of 16 equal parts (i.e., triangles). Hence, this figure represents a fraction 
Now, these figures can be matched correctly as
(a) (ii), (b) (iv), (c) (i), (d) (v), (e) (iii)
