Answer 1

Step-by-step explanation:

A:B::C:D

16X 3 : 12 X x

48 = 12x

x= 48/12

x=4

Answer 2

The missing number is 4.

GIVEN

16:?::12:3.

TO FIND

The missing number.

SOLUTION

We can simply solve the above problem as follows;

We are given a mathematical expression;

16:? :: 12:3

We know that the sign '::' is a sign of proportionality.

The proportionality sign represents the equality of two ratios.

Let the missing number be,'b'

Therefore,

16:b:: 12:3

Applying the proportionality formula,

Product of the extremes = Product of means

Where,

Extremes terms = 16 and 3

Mean terms = b and 3

Therefore,

16 × 3 = b × 12

$b = \frac{16 \times 3}{12}$

b = 4

Hence, The missing number is 4.
