Answer»

(i) 250/400 = \(\frac{5\times 50}{8\times 50}\) = 5/8

Two more fractions are 25/40, 30/48

(ii) 180/200 = \(\frac{9\times20}{10\times20}\) = 9/10

Two more fractions are 18/20, 27/30

(iii) 660/990 = \(\frac{2\times 330}{3\times330}\) = 2/3

Two more fractions are 20/30, 200/300

(iv) 180/360 = \(\frac{1\times 180}{2\times180}\) = 1/2

Two more fractions are 20/40, 30/60

20/40, 30/60 = \(\frac{2\times 110}{5\times110}\) = 2/5

(v) 220/550 = \(\frac{2\times 110}{5\times110}\) = 2/5

Two more fractions are 20/40, 40/100

Now these can be matched as

(i) – (d),

(ii) – (e),

(iii) – (a),

(iv) – (c),

(v) – (b)
