The correct answer is 1/10.

Caitlin Armstrong · Answer 2

This equation can be solved using simple algebra.

Let's say that the missing is A, hence replacing the box with the A, giving:

35.4 x A = 3.54

We then could divide both sides of the equation - left hand side (35.4 x A) and the right hand side (3.54) - with 35.4, as we would want to get rid of this number from the left to leave us with A only. The equation then becomes:

A = (3.54/35.4)

Simply use the calculator and you'd get 1/10.

Which is C!
