document.write( "Question 1204475: On a wall 78 2/5 cm wide, Peter is going to hang two pictures beside each other, each measuring 12 1/2 cm wide. He will leave 2 3/5 cm in between the pictures. He plans to use two nails to hang each picture, and will centre these nails leaving 4 1/2 cm between each pair. How far, in cm, from the end of the wall (on either side) will the first nail be placed? \n" ); document.write( "

Draw a picture of the wall. Note that since the arrangement on the wall is symmetrical, you really only need a picture of half of the wall.\r
