Question

51:85 proportion 57:x

Answer 1

Hey Mate,

Let us take the unknown number to be "x".

We also know that product of means is equal to the product of extremes, i.e., the product of the second and third terms is equal to the product of the first and fourth terms.

Then,

51x = 57 x 85

=> 51 x = 4845

=> x = 4845/51

=> x = 95

Therefore, x = 95 is the solution for 51 : 85 :: 57 : x.

Hope it Helps!

Answer 2

Answer:

x = 95

Step-by-step explanation:

Remember to rewrite the give equation before beginning your actual calculations.

Probably we need to find the value of ' x '.

51 : 85 : : 57 : x

We can replace the sign of proportion(::) by equal to (=),

51 : 85 = 57 : x

Exchanging LHS with RHS,

57 : x = 51 : 85

Replacing (:) by (/),

57 / x = 51 / 85

= > x = ( 57 * 85 ) / 51

= > x = 95

Therefore,

x = 95
