given a linear ratio = a : b, then the corresponding area ratio is

a² : b²

Here the linear ratio of their edges = 3 : 1, hence

ratio of surface areas = 3² : 1² = 9 : 1

Add 2/3 yards 4/9 yard and 23/36 yard and please show work
natta225 [31]

Answer:

  7/4 yard

Step-by-step explanation:

36 is a suitable common denominator for expressing these fractions. All measures are in yards.

  2/3 + 4/9 + 23/36 = (12·2)/(12·3) + (4·4)/(4·9) + 23/36

  = 24/36 + 16/36 + 23/36

  = 63/36 = (9·7)/(9·4)

  = 7/4 = 1 3/4 . . . . . yards
