- to get close to the answer.
- is to make the problem easier.
- is to know what to expect from our calculations.
1.36 L of O.J. (Orange Juice) and there's 4 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 can use long division :
0.34
