Question

Find the number that completes the following problem:42____ ×6 = 2,538

Answer 1

ANSWER

3

EXPLANATION

We want to find the number that completes the problem:

42_ * 6 = 2538

To do this, we simply have to divide both sides by 6, so that we're left with the number 42_ on the left hand side:

$\begin{gathered} \frac{42_{\text{\_}}\cdot\text{ 6}}{6}\text{ = }\frac{2538}{6} \\ 42_{}\text{ \_ = 423} \end{gathered}$

By comparing, we see that the missing number is 3.
