Question

WHAT IS RATIO OF MEAN PROPORTION BETWEEN 4.8 AND 10.8 AND THIRD PROPORTION OF 0.4 AND 2.4

Answer 1

Answer:

.27/1

Step-by-step explanation:

let mean proportion =X

x^2= 4.8*10.8=15.6

X= 3.94

third proportion is (2.4*2.4)/0.4=5.76/.4=14.4

ratio is = 3.94/14.4= 0.27

Answer 2

Mean proportion between 4.8 and 10.8 is 7.2

Third proportion of 0.4 and 2.4 is 14.4

Solution:

MEAN PROPORTION BETWEEN 4.8 AND 10.8

The mean proportion between a and b is $\sqrt{ab}$

Therefore,

Mean proportion between 4.8 and 10.8 is:

Here a = 4.8 and b = 10.8

$Mean\ proportion = \sqrt{4.8 \times 10.8}\\\\Mean\ proportion = \sqrt{51.84}\\\\Mean\ proportion = 7.2$

THIRD PROPORTION OF 0.4 AND 2.4

Let the third proportional to the two numbers 0.4 and 2.4 be x

According to third proportion,

0.4 : 2.4 : : 2.4 : x

Which means,

$\frac{0.4}{2.4} = \frac{2.4}{x}\\\\0.4x = 2.4 \times 2.4\\\\0.4x = 5.76\\\\x = 14.4$

Thus, third proportion of 0.4 and 2.4 is 14.4
