Question

2.4= -t --- 4.5 Can anyone help me?

Answer 1

Here, 2.4 / 4.5 = -t
In order to convert it into more simpler form ,you need to multiply both numerator and denominator by 10, & change the sign, 

t = -24/45
t = -8/15
t = -0.53

In short, Your Answer would be: -0.53 or -8/15

Hope this helps!

Answer 2

You have to multiply 4.5 for both side to eliminate the denominator and then change the sign

(2.4*4.5)= -t

10.8=-t
-10.8=t
