Why we estimate
-to get close to the answer.
-is to make the problem easier.
-is to know what to expect from our calculation.
What I estimate and calculate should be close.
1.36 L of O.J. there is for of you.
a) estimate how much you each get.
b) calculate how much you each get.
2.0 divided by 4 would equal 0.5 and that is 1/2 over estimating.
1.0 divided by 4 would equal 0.25 and that is 1/4 under estimating.
1.3 divided by 4 would equal 0.3 (0.36)
1.6 divided by 4 would equal 0.4 (0.46)
or you could use long division
o.34
41.36
-0
______
1.3
-12
______
16
-16
______
0
So then the answer would be that each person would get 0.34 L of O.J.
Here is the next question.
24.6
373.8
-6
______
13
-12
______
18
The answer would be 24.6
Here's a good website you could find more about how to divide decimals http://www.coolmath.com/prealgebra/02-decimals/10-decimals-dividing-by-decimal-01.htm
This is a video on dividing decimals.
This is our home work.
5.4 divided by 0.6
Use number line and estimating and long or short division.
