“a patchwork blanket is made up of 10 identical squares. liam has made 14 squares, raj has made 12 squares and gemma has made 15 squares. “ how many patchwork blankets have they made between them ? give your answer as a mixed number

Well, assuming that Liam, Raj, and Gemma all have squares identical to each other, then you would first add them all up. 14+12+15=41. Then, you would divide the total number of squares by the number of squares in a quilt. 41/10=4.1, or 4 1/10.
Hope this helps!
