Question 1197926
<br>
I'll leave the actual calculations to you; you won't get any benefit from working this problem if I do them for you.<br>
(1) total width of wall: 82 3/5 cm<br>
(2) total width of the four pictures and the three spaces between them: 4 times 10 1/4 cm, plus 3 times 3 4/5 cm<br>
(3) distance from one end of the wall to edge of first picture: half of the difference between (1) and (2) [the four pictures are centered on the wall]<br>
(4) distance from the edge of each picture to the closest nail used to hang the picture: half the difference between 10 1/4 cm and 5 1/4 cm [the two nails on each picture are centered on the picture]<br>
(5) distance from end of wall to first nail: (3) plus (4)<br>
