Sewing

The lady cut off one half of cloth. She needed three-quarters of this piece to sew a skirt. What part of the original piece of cloth still remained?

Result

x =  0.625

Solution:

a=12 34=38=0.375  x=1a=10.375=58=0.625a=\dfrac{ 1 }{ 2 } \cdot \ \dfrac{ 3 }{ 4 }=\dfrac{ 3 }{ 8 }=0.375 \ \\ \ \\ x=1 - a=1 - 0.375=\dfrac{ 5 }{ 8 }=0.625
