solve the proportions .. round to the nearest tenth
X/9=15/2 29/U=75/44 9.47/P=3.33/1

You can put this solution on YOUR website!
X/9=15/2 29/U=75/44 9.47/P=3.33/1

1.
X%2F9=15%2F2
X+=+%2815%2A9%29%2F2
X+=+135%2F2
X+=+67.5
X+=+70+%28round+to+the+nearest+tenth%29
2.
29%2FU=75%2F44
Invert the fractions above:
U%2F29+=+44%2F75
U+=+%2844%2A29%29%2F75
U+=+17.0133333
Round to the nearest tenth:
(forgive me if I'm wrong here, I haven't rounded to the nearest tenth for 10 yrs!)
U+=+20

3.
9.47%2FP=3.33%2F1
Inverse the fractions above
P%2F9.47+=+1%2F3.33
P+=+%281%2A9.47%29%2F3.33
P+=+2.84
Round to the nearest tenth = 0?
