Remember,
To subtract 2/3-1/2 you have to make them equivalent
2/3×2-1/2×3 = 4/6 - 3/6=
1/6
That is true because factors of 40 are 10,5
The diagram shows a lawn with the north side measuring 50 units and the west side measuring 28 units. The deck is scaled down by a factor of 1/5.
This is because the ratio of the length of the lawn to that of the deck is 1 : 5.
Hence we can now ca
