what is the total length if you have 12 strips of metal that are each 4ft. 3 7/8 in. long
+130513 12 * [ 4ft + [3 + 7/8] inches ]
12* 4 = 48 ft
12 * [3 + 7/8] = 12 * [3.875 ] = 46.5 in ......46.5 / 12 = 3.875 ft and .875ft = 10.5 in
So we have
[48 + 3] ft + 10.5 in =
51 ft 10 + 1/2 inches
Just convert feet into inches first, so we have,
4 X 12 +3.875=51.875, then just multiply by 12 strips, and you get,
12 X 51.875=622.50 length of 12 strips in inches. Then just divide this by 12 to give you feet.
622.50 / 12=51.875 feet, total length of 12 strips of metal.
Notice that 7/8=.875 in decimal notation.
OR, we could have done simpler by just dividing 3.875/12 +4=4.322916666666....X 12=51.875 feet.
