Answer:
Solution:
(i) mean proportional between 16 and 4
=\sqrt{16\times4}=
16×4
=\sqrt{64}=
64
= 8
(ii) mean proportional between 3 and 27
=\sqrt{3\times27}=
3×27
=\sqrt{81}=
81
= 9
(iii) mean proportional between 0.9 and 2.5
=\sqrt{0.9\times2.5}=
0.9×2.5
=\sqrt{\frac{9}{10}}\times\sqrt{\frac{25}{10}}=

= 1.5
(iv) mean proportional between 0.6 and 9.6
=\sqrt{0.6\times9.6}=
0.6×9.6
=\sqrt{\frac{6}{10}}\times\sqrt{\frac{96}{10}}=
