Question

5.65 times 3.4 estimate

Answer 1

We can round 5.65 up to 6 and 3.4 down to 3.
3 * 6 = 18
now let's see how close our estimate is to the real answer
5.65 * 3.4 = 19.21
Our answer was pretty close to the real answer!

Hope I helped!

Answer 2

You estimate 5.65 to be 10 and 3.4 to be 0 and you multiply. The answer will then be 10.
