no. of boys : no.of girls
100 : 140
to get the simplest ratio you gotta divide both with a common factor
Because both 100 and 140 share a common factor of 20
the simplest ratio will be
100/20 : 140/20
5:7
5:7 is the simplest ratio
this is the answer y=−1/2x+45/2
Recall that
where is the angle between the vectors whose magnitudes are , respectively.
We have
We add 0.00055+0.00104 together.
0.00104+0.00055= 0.00159
I hope this helps!
