Question

Here is a table which gives the information about the total rainfall for several months compared to the average monthly rains of a town. Write each decimal in the form of rational number `p/q`.

Month Above/Below
normal (in cm)
May 2.6924
June 0.6096
July – 6.9088
August – 8.636
Sum

Solution

(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]
