Question

(1.15)x3.2

Answer 1

Here's a trick, just do long multiplication and ignore the decimals. So do: 115x32, which equals 3680. And then count the decimal places of both and add them, 1.15 has 2 decimal places and 3.2 has 1, 1 + 2 = 3. Then move the decimal place 3 spots to the right making it 3.680 or 3.68
