Problem

The following area model shows 3, times, 69 broken into parts.
The image is not drawn to scale.
An area model using a rectangle of 2 unequal parts, a first part labeled A with a width of 3 and a length of 60 and a second part to the right, labeled B, has the same width as part A and a length of 9.
Find the area of each part.
A, equals
  • Your answer should be
  • an integer, like 6
  • an exact decimal, like 0, point, 75
  • a simplified proper fraction, like 3, slash, 5
  • a simplified improper fraction, like 7, slash, 4
  • a mixed number, like 1, space, 3, slash, 4
B, equals
