Answer:

This is an example of inverse proportion, or inverse variation.

To change a proportion into an equation, multiply by a constant and then use the values given to find the value of the constant.

a

1

b

a

=

k

b

k

=

a

b

Find the value of k, using the a and b given.

k

=

3

×

=

12

So,

a

=

12

b

can also be written as

b

=

12

a

When

a

=

,

b

=

Answer:

B = 5

Step-by-step explanation:

from the question...

When B is inversely proportional to A,

then,

B = R/A ••••••••••••(i)

(Where we assume R is a constant)

When A= 2 then B =3.5.

now, from equation 1...

3.5 = R/2

R= 7 (after solving)

Since R is a constant,

then,

B = R/A for all values of B and the corresponding value of A.

therefore, when A= 1.4

then B=?

now,

B= 7/1.4

B=5 Ans.

I HOPE THIS SOLUTION MAY HELP YOU.
