You can put this solution on YOUR website!
First, find the length of the shortest piece, s in meters
+s+%2F+3.5+=+1+%2F+%281+%2B+2+%2B+3+%2B+4%29+
+s+%2F+3.5+=+1+%2F+10+
+s+=+3.5%2A%281%2F10%29+
+s+=+.35+
+2s+=+.7+
+3s+=+1.05+
+4s+=+1.4+
The longest piece is 1.4 m long
check answer:
+s+%2B+2s+%2B+3s+%2B+4s+=+.35+%2B+.7+%2B+1.05+%2B+1.4+
+10s+=+1.05+%2B+1.05+%2B+1.4+
+10s+=+3.5+
OK
