So, don’t expect me to get this exactly right. I tried.
My explanation:
The rib ion originally started at 6 feet
You first cut 3 2/3 off, so your now left with 7/3 or 2 1/3 (simplified)
Now your left with 2 1/3.
Then you cut a second piece off, 2 5/6 inches….so 2 5/6 minus 2 1/3 = 1/2
So you should have about 1/2 of a ribbon left.
(I tried btw. I’m very sleepy rn.)
