Hello! First off, I want to sincerely thank everyone on this forum. I have been lurking around in obscurity on here for some time, and the information I've gleaned from yall has helped me tremendously in my first and final year of competitive Number Sense. As a 1A competitor, I do not have access to (m)any resources. In fact, I am my own coach. My scores, though meager by most standards, would be GREATLY diminished if not for the folks here. Again, thank you!!!
I'd also like to ask a question... On this year's tests, I keep running into questions like these...
1/10 + 1/40 + /1/88 = ?
1/18 + 1/54 + 1/108 = ?
Is there a better way to do these than just getting the LCD?
Thanks!
