Concept:

Mathematical expression is a mathematical relation or statement or term involves various mathematical quantities, numbers, mathematical operations, variable and other mathematical components etc.

We have to replace the required number by a variable and have to form suitable mathematical expression using the conditions.

Given:

Given that product of one unknown number and -4/35 is 8/105.

Find:

The value of that above unknown number.

Solution:

Let x should be multiplied with -4/35 in order to get the value of 8/105.

So the according to given condition the mathematical expression is,

x*(-4/35) = 8/105

On solving we get the value of x which is the required answer.

-4x/35 = 8/105

-4x = (8/105)*35, multiplying 35 to both sides

-4x = 8/3

-x = 8/(3*4), on dividing 4 from both sides.

-x = 2/3

x = 2/3, multiplying -1 to both sides

Hence 2/3 should be multiplied with -4/35 wo get 8/105.
