Step-by-step explanation:
Use this formula
if a:b::c:d
then it will satisfy
a×d=b×c
1)
16, 4, 32, 8
16×8=128
4×32=128
Hence in proportion
Similarly
2)
16, 30, 24, 45
16×45 = 720
30×24=720
Hence in proportion
3)
18, 10, 9,5
18×5=90
10×9=90
Hence in proportion
4)
3, 4, 2, 6
3×6=18
4×2=8
Here not in proportion....
