Question

divide 18 in the ratio 3:6​

Answer 1

First,add the numbers in the ratio
3+6=9

Now,(3/9)*18=3*2=6
(6/9)*18=6*2=12

Mark me as the brainliest please...

Answer 2

★ How to do :-

Here, we are given with some number which is to be divided between two people. We are asked that how much number doen each of them get. So, here we are going to solve the problem using some other concepts such as variables and the numbers should be shifted from one hand side to the another. The variables should be written with both the part of the ratio anf then add them. Later, we can shift the numbers from one side to other. Ee can fins the value of each. So, let's solve!!

$\:$

➤ Solution :-

${\tt \leadsto 3 : 6 = 18}$

Insert a variable x to both the parts of ratio.

${\tt \leadsto 3x + 6x = 18}$

Add both numbers having a same variable.

${\tt 9x = 18}$

Shift the number 9 from LHS to RHS, changing it's sign.

${\tt \leadsto x = \dfrac{18}{9}}$

Simplify the fraction to get the value of x.

${\tt \leadsto x = 2}$

$\:$

Now, let's calculate that how much number does each person get.

Number of first person :-

${\tt \leadsto 3x = 3 \times 2}$

Multiply thr numbers to get the answer.

${\tt \: \: \: \: \: \leadsto \pink{\underline{\boxed{\tt 6}}}}$

Number of second person :-

${\tt \leadsto 6x = 6 \times 2}$

Multiply thr numbers to get the answer.

${\tt \: \: \: \: \: \leadsto \pink{\underline{\boxed{\tt 12}}}}$

$\:$

Verification :-

${\tt \leadsto 3x + 6x = 18}$

Substitute the values of variable.

${\tt \leadsto 6 + 12 = 18}$

Add the values on LHS.

${\tt \leadsto 18 = 18}$

So,

${\tt \leadsto LHS = RHS}$

$\:$

Hence verified !!
