Solve for the missing part of the proportion. 13/27 = ? /324

156

Step-by-step explanation:

Solve for the missing part of the proportion. 13/27 = ?/324

To solve the missing part of this proportion;

13/27 = ?/324

The first step to take is to cross multiply

(13 will multiply 324 and ? will multiply 27)

27 × ?   =   13 ×  324

27 × ?  =  4212

Then the next step is to divide both-side of the equation by 27

27 × ?   /   27     =      4212   /  27

(On the left-hand side of the equation, 27 will cancel out 27, we will be left with ?,  and on the right-hand side of the equation 4212 by 27 to get 156)

?    =   156

Therefore, the missing part of the proportion is 156
