WILL FAN AND MEDAL!!!!!! Ming made a triangular picture frame out of cardboard. The sides of the frame are 6.75 in., 6.75 in., and 8.375 in. Ming uses the addition below to determine the amount of string she needs to decorate the edges of the frame.

    Which explains Ming’s error? She should have included the decimal in 6.75 and aligned the decimal points to add 6.750 + 6.750 + 8.375 = 21.875. She forgot to put the decimal point in two of the numbers: 0.675 + 0.675 + 8.375 = 9.725. She added 6.75 twice, and she should have only added it once: 6.75 + 8.375 = 15.125. She should have placed a zero placeholder after the decimal point to add 6.075 + 6.075 + 8.375 = 20.525.

    The mistake is where she should have added 6.75 + 6.75 + 8.375. When your adding decimal numbers together, you have to add accordingly.

    the first one because it should be 6.75 not 675 and it should be aligned like this 6.75 6.75 8.375
