Q.6 Find the ratio of the following:

(a) 81 to 108

(b) 98 to 63

(c) 33 km to 121 km

(d) 30 minutes to 45 minutes

(a) 81 to 108

(b) 98 to 63

(c) 33 km to 121 km

(d) 30 minutes to 45 minutes

(a) 81 to 108 = \(\frac{81}{108} = \frac{81÷27}{108÷27} = \frac{3}{4} \)

(b) 98 to 63 = \(\frac{98}{63} = \frac{98÷7}{63÷7} = \frac{14}{9} \)

(c) 33 km to 121 km = \(\frac{33 km}{121 km} = \frac{33÷11}{121÷11} = \frac{3}{11} \)
