5. ERROR ANALYSIS Describe and correct the error in finding the sum of the number
(25 x 10"] + 153 x 10" = (25+53) x 110' x 10°)
78 x 10"

  (25 × 10") + 153 × 10" = (25 +153) × 10" = 178 × 10" = 1780"

Step-by-step explanation:

a) Numbers are miscopied: the numbers in parentheses should be (25 +153). Of course, the sum of these should be 178, not 78.

b) The common factor 10" is somehow expanded to 110' x 10°. It should be 10".

The sum should be ...

  (25 × 10") + 153 × 10" = (25 +153) × 10"

  = 178 × 10" = 1780" . . . . . correct sum

Maybe the middle step is an attempt to convert to feet.

  1780" × (1')/(12") = (148 1/3)' = 148' 4"
