Question

find the no which bears the same ratio to 5 so that 8 does to2

Answer 1

Answer:

20 is the no.

✨ Step-by-step explanation:

Let the no be x.

Then,

X : 5 :: 8 : 2

➡️ Product of means = product of extremes

➡️5 ☓ 8 = 2x

➡️40= 2x

➡️ x = 40/2 or x = 20

Hence,

The no is 20

Answer 2

Answer:

Step-by-step explanation:

Let the number be x.

Then x:5::2:x, or

x^2=10 or x = 10^0.5 = sq root(5*2)

Check: sq root(10)/5 = 0.6324.

2/sq root (10) = 0.6324. Both are the same.

ALL THE BEST DEAR.
