hello
to solve this problem, we need to find the property of equality
let the unknown number be represented by x
![4=1* x](https://img.qammunity.org/2023/formulas/mathematics/college/bdtfjk2w715ttxfbnc81bswnsco5vt5fl1.png)
to solve for x, divide both sides of the equation by 1
![\begin{gathered} 4=1x \\ (4)/(1)=(1x)/(1) \\ x=4 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/q0kt0j6g3ggrldi172f2eby1s98ull6o89.png)
the number here is 4
the property used to get the answer is division property of equality
