Answer:
a) 84 / -100
b)-115 / 85
c) -15 / 55
d) -152 / 64
Step-by-step explanation:
a) - 21 / 25 as a rational number with denominator -100
so we have to multiply the numerator and the denominator with -4
-21 x -4 / 25 x -4 = 84 / -100
b) 23 / -17 as a rational number with denominator 85
so we have to multiply the numerator and the denominator with -5
23 x -5 / -17 x -5 = -115 / 85
c)3 / -11 as a rational number with denominator 55
so we have to multiply the numerator and the denominator with -5
3 x -5 / -11 x -5 = - 15 / 55
d) - 19 / 8 as a rational number with denominator 64
so we have to multiply the numerator and the denominator with 8
-19 x 8 / 8 x 8 = -152 / 64
Here's your answer mate!
