Find the difference:(i) (6/7) – (9/11)(ii) 8 – (5/9)

1.	Find the difference:(i) (6/7) – (9/11)(ii) 8 – (5/9)
Answer» (i) Given (6/7) – (9/11) To find the difference we have to make it equivalent fractions. Taking LCM of 7 and 11 is 77. Now converting the given fractions into equivalent fractions with denominator 77. Equivalent fractions are (66/77) and (63/77) (6/7) – (9/11) = (66/77) – (63/77) = (66 – 63)/77 = (3/77) (ii) Given 8 – (5/9) To find the difference we have to make it equivalent fractions. Taking LCM of 1 and 9 is 9. Now converting the given fractions into equivalent fractions with denominator 9. Equivalent fractions are (72/9) and (5/9) 8 – (5/9) = (72/9) – (5/9) = (72 -5)/9 = (67/9)

Answer»

(i) Given (6/7) – (9/11)

To find the difference we have to make it equivalent fractions.

Taking LCM of 7 and 11 is 77.

Now converting the given fractions into equivalent fractions with denominator 77.

Equivalent fractions are (66/77) and (63/77)

(6/7) – (9/11)

= (66/77) – (63/77)

= (66 – 63)/77

= (3/77)

(ii) Given 8 – (5/9)

To find the difference we have to make it equivalent fractions.

Taking LCM of 1 and 9 is 9.

Now converting the given fractions into equivalent fractions with denominator 9.

Equivalent fractions are (72/9) and (5/9)

8 – (5/9)

= (72/9) – (5/9)

= (72 -5)/9

= (67/9)
