Answer 1

Three ** /3) has has

Answer 2

Answer:

Assuming that the longest blue whale on record  was about 18 scuba divers in length and a scuba diver is 6 feet length, we want to estimate the length of the whale.

Length of the whale = 18*6

You can multiply mentally by  using compensation. Substitute a number for 18 that is easy  to multiply.

20*6 = 120

Now adjust. Subtract 2 groups of 6, or 12.

120 - 12 = 108

and that is the length of the whale in feet
