(i) Given (5/7)
To get denominator -14 we have to multiply both numerator and denominator by -2
Then we get, (5/7) × (-2/-2)
= (-10/-14)
Therefore (5/7) as a rational number with denominator -14 is (-10/-14)
(ii) Given (5/7)
To get denominator 70 we have to multiply both numerator and denominator by -2
Then we get, (5/7) × (10/10)
= (50/70)
Therefore (5/7) as a rational number with denominator 70 is (50/70)
(iii) Given (5/7)
To get denominator -28 we have to multiply both numerator and denominator by -4
Then we get, (5/7) × (-4/-4)
= (-20/-28)
Therefore (5/7) as a rational number with denominator -28 is (-20/-28)
(iv) Given (5/7)
To get denominator -84 we have to multiply both numerator and denominator by -12
Then we get, (5/7) × (-12/-12)
= (-60/-84)
Therefore (5/7) as a rational number with denominator -84 is (-60/-84)
