First add 12 to both sides to get 5a = 10
Then divide both sides by 5 to get a = 10/5
Simplify and get a = 2

Answer:

The missing number is 4

Step-by-step explanation:

Given

21 x 39 x _____ x 19 divided by 12 = 5187

Required

Fill in the gap

Let the missing number be represented with y; So, the expression becomes

\frac{21 * 39 * y * 19 }{12} = 5187

Multiply both sides by 12

12 * \frac{21 * 39 * y * 19 }{12} = 5187 * 12

21 * 39 * y * 19 = 62244

Rearrange the expression on the left hand side

21 * 39 * 19 * y = 62244

15561 * y = 62244

Divide both sides by 15561

\frac{15561 * y}{15561} = \frac{62244}{15561}

y = \frac{62244}{15561}

y = 4

Hence, the missing number is 4
