Question

Reduce each of the following ratios to their lowest terms : (i) 1 hour 20 min : 2 hours

Answer 1

Answer=2:3

Step:

1)We write it as :
1×60 min+20 min : 2×60 min
=>60 min + 20 min:120 min
=>80 min : 120 min
=>80:120
2)Convert it into fraction
=>$\frac{80}{120}$

3)Find HCF of 80 and 120
=>HCF of 80 and 120=40.

4)Divide both numerator and denominator by 40. We get
=>$\frac{80 \div 40}{120 \div 40}$
=>$\frac{2}{3}$
=>2:3
