This means making the fraction reduced to its lowest term
example=
make the fraction 18xz/4z simpler
the z cancels each other making it remaining 18x/4
2 can go in x as in 18
=9x/2
so the simpler form of the fraction 18xz/4z
=9x/2
1. 8+5=13
2. 13 x 3 x 10 = 13 x 30 = 390
Using the information above transform the ratio 8:5.
8 x 30 : 5 x 30
If you do this, you'll end up with the ratio:
240 : 150
