Answer 1

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
