Masja [62]

Answer:

I did my work, and I got 37 scarves. I feel really bad bc I am not 100% sure, and I hate when I am not 100% sure.

Step-by-step explanation:

For if you need to show your work:

33 pieces of blue fabric --> it can make 11 scarves exactly

37 pieces of green fabric --> it can make 12 scarves, with 1 piece of fabric left over

41 pieces of red fabric --> it can make 13 scarves, with 2 pieces of fabric left over

Left over fabric --> there are 3 pieces of fabric left over; 1 green and 2 red. This results in 1 more scarf

So lets add up our scarves: 11 scarves + 12 scarves + 13 scarves + 1 more scarf

That equals 37 scarves!

I hope this helps. Please <em><u>mark brainliest</u></em><em>, </em>I would really appreciate it if you did
