Question

Find the mean proportional between
(i) 144 and 225
(ii) 0.32 and 0.08
(iii)1/36 and 1/9
​

Answer 1

Answer:

1) Let the mean between 144 and 225 is X

144:X =X:225

= x² = 32400

= x = 180

180 is the mean proportional between 144 and 225

2) 0.08:x=x: 32.

X^2= 32.08

X^2= 0.0256

X = 0.16

0.16 is the mean proportional of 0.32 and 0.08

3) 1/36 and 1/9

= √( 1/9 ×1/36 )

= 1/3 × 1/6

= 1/18

Answer 2

Answer:

• 180
• 0.16
• 1/18
