उत्तर
(i) May = 2.6924
= `26924/10000` ...[Remove decimal]
`\implies p/q = 6731/2500 "cm"` ...[After dividing numerator and denominator by 4]
(ii) June = 0.6096
= `6096/10000` ...[Remove decimal]
`\implies p/q = 381/625 "cm"` ...[After dividing numerator and denominator by 16]
(iii) July = – 6.9088
= `-69088/10000` ...[Remove decimal]
`\implies p/q = -4318/625 "cm"` ...[After dividing numerator and denominator by 16]
(iv) August = – 8.636
= `-8636/1000` ...[Remove decimal]
`\implies p/q = -2159/250 "cm"` ...[After dividing numerator and denominator by 4]
