Question

Express 2/-3 as a rational number with denominator (1) -15 (2) 18

Answer 1

$(1) \: - 15 \\ \frac{2}{ - 3} \times \frac{5}{5} = \frac{10}{ - 15} \\ (2)18 \\ \frac{2}{ - 3} \times \frac{ - 6}{ - 6} = \frac{ - 12}{18}$

Answer 2

Answer:

1). -15

-2/3 = x/15

x=(-15/3)×(-2)

= -5×(-2)

= 10

== 10/15

2). 18

= -2/3=x/18

= x= (18/3)×(-2)

= 6×(-2)

= -12

= -12/18
