Answer: The number is 35

If 2/5 of a number is 14, then we will perform a function of cross multiplication in order to determine the missing number.

Step-by-step explanation:

Let the missing number = y

To perform a cross multiplication, firstly, we multiply the numerator of first fraction by the denominator of the second fraction.

Secondly, we multiply the denominator of the first fraction by the numerator of the second fraction. Then, the resulting values are divided by each other to get a final numerical value.

Therefore, the missing number (y) will the denominator of the second fraction i.e. 14/y . The first fraction is 2/5.

Thus,

2/5 of 14/y

2/5= 14/y

(2 x y) = (5 x 14)

(2y) = (70)

2y = 70

Since we are looking for value of y, divide both sides by the value beside y

Thus,

2y/2 = 70/2

y = 35

Therefore, the missing number is 35
