![\large\boxed{100_{10}=1100100_2}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7B100_%7B10%7D%3D1100100_2%7D)
Step-by-step explanation:
![100:2=50\qquad rest=0\\50:2=25\qquad rest=0\\25:2=12\qquad rest=1\\12:2=6\qquad rest=0\\6:2=3\qquad rest=0\\3:2=1\qquad rest=1\\1:2=0\qquad rest=1\\\\\text{We write from the bottom up}\\\\100_{10}=1100100_2](https://tex.z-dn.net/?f=100%3A2%3D50%5Cqquad%20rest%3D0%5C%5C50%3A2%3D25%5Cqquad%20rest%3D0%5C%5C25%3A2%3D12%5Cqquad%20rest%3D1%5C%5C12%3A2%3D6%5Cqquad%20rest%3D0%5C%5C6%3A2%3D3%5Cqquad%20rest%3D0%5C%5C3%3A2%3D1%5Cqquad%20rest%3D1%5C%5C1%3A2%3D0%5Cqquad%20rest%3D1%5C%5C%5C%5C%5Ctext%7BWe%20write%20from%20the%20bottom%20up%7D%5C%5C%5C%5C100_%7B10%7D%3D1100100_2)
find the least common multiple of 25 and 30, which is 150
so they will flash at the same time every 150 seconds which equals 2.5 minutes
I'm pretty sure its 127.8
I don’t know the answer I need these points soooo yeah
