Question

Find the unknown of the value of proportion x : 3 = 0.4 : 0.5

Answer 1

Step-by-step explanation:

Hello!

Here is the detailed explanation for your quesstion..

• As we know that when 4 numbers are in proportion, we can express them as, a:b=c:d

• In simple words we can express them as

a/b=c/d.

• Here the values of a,b,c and d are x,3,0.4 and 0.5.

• Substituting the values of a ,b , c and d with their numerical values ,we get

x/3=0.4/0.5

• By doing cross multiplication,we get

x*0.5=0.4*3

• Or, x=(0.4*3)÷0.5

• x=1.2÷0.5

• x= 2.4

Thus the final value of x is 2.4

And the missing part of the proportion is 2.4.

Thus 2.4 is the required answer of the question.

Hope it helps!
