Similarity of two triangles

The KLM triangle has a side length of k = 6.3cm, l = 8.1cm, m = 11.1cm. The triangle XYZ has a side length of x = 8.4cm, y = 10.8cm, z = 14.8cm. Are triangle KLM and XYZ similar? (write 0 if not, if yes, find and write the coefficient of a similarity)

Correct result:

q =  1.3333


k=6.3 cm l=8.1 cm m=11.1 cm  x=8.4 cm y=10.8 cm z=14.8 cm  k<l<m x<y<z q1=x/k=8.4/6.3=431.3333 q2=y/l=10.8/8.1=431.3333 q3=z/m=14.8/11.1=431.3333  q1=q2=q3  q=q1=1.3333=43
