Question

5. Express 4/-7 as a rational number with denominator,
(1) 84
(ii) - 28


​

Answer 1

Step-by-step explanation:

(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)
