Question

Solve the proportion 25:q=5:2 for q.​

Answer 1

Answer:

= 25 : q : : 5 : 2

= 5 x q = 2 x 25

= 5q = 50

= q = 50/5

= q = 10

Verifying:

Inputting the values:

= 25 : 10 : : 5 : 2

= 25 x 2 = 10 x 5

= 50 : : 50

Answer 2

To find : the value of $q$ .

Given ratio : $25: q= 5: 2$

Solution :

• As we can see that in the given ratio of proportion one of the ratio is missing.

• To find ratio we can write $25: q= 5: 2$  as,  $\frac{25}{q}=\frac{5}{2}$

• Transposing  like terms we get,

      $\Rightarrow \quad q=\frac{25 \times 2}{5}$

• On simplifying we get,

     $\begin{array}{l}\Rightarrow q=5 \times 2 \\\Rightarrow q=10\end{array}$

Hence, value of $q$  is $10$.
