Find how much it grew:

53 - 20 = 33 inches.

Divide the amount it grew by the original length

33/20 = 1.65

Subtract 1:

1.65 - 1 = 0.65

Multiply by 100 for percent:

0.65 x 100 = 65%

The percent increase is 65%

Robert is making 5 batches of lemonade. Each batch requires 2 1\3 quarts of water.
svetlana [45]
2 1/3 quarts per batch, and five batches, so you multiply 2 1/3 x 5.

2 1/3 = 7/3   and   5 x 7/3 = 35/3 which simplifies to 11 2/3, so D. is the answer. 

If you would like a more detailed answer just ask.
