When you are estimating sums and differences of fractions by rounding how do you know to round it to zero half or one?
Let's say that you are rounding 2/5. You find half of 5 which is 2.5. Then you see if 2 is closer to 0, 2.5/5, or 1. It is closer to 2.5, so you would say that 2.5 is half of five, so your answer is 1/2. If you are doing 1/7, 1 is obviously closer to 0, so your answer would be 0.

How is estimating quotients different from estimating products?
Estimating quotients is like trying to guess how many slices of cake you'll get from a whole cake, while estimating products is like trying to figure out how much money you'll have after buying a certain number of cakes. In both cases, you're making an educated guess based on the numbers involved, but the end result is either a quotient (division) or a product (multiplication). So, in a nutshell, estimating quotients involves dividing and estimating products involves multiplying.

When estimating three digit numbers how do you round to the nearest tenth?
To round any number, look at the digit to the right of the place you are rounding to. If the digit is 5 or more, change the digit in the place you are rounding to to the next higher digit. If the digit to the right of the place you are rounding to is less than 5, leave the digit in the place you are rounding to as it is. Change all digits to the right of the place you rounded to to zeros.
How do you round fractions?
you round fractions by rounding up or down, you can decide to do this when you look at the numerator and decide if it is half of the denominator, if it is half or more than half, you round up. If it is less than half you round down. Another way you can round fractions is dividing the top number by the bottom number (with a calculator), then if the decimal part is 5 or more, round up! (if the decimal is less than 5, round down.)
What is the difference in what you have to do for rounding and estimating?
Estimating is just an educated guess. For example, if you have to solve the problem 102.17 plus 266.18, you would make an educated guess. An educated guess would be 100+ 270 which equals 370. When you are rounding, you will usually get instructions to round a certain number. It is knowing the exact value, but finding the nearest whole number. For example: Round to the nearest hundredth 4.6781 If you are rounding to the nearest hundredth, you are trying to round the number 8, since it is in the hundredths spot. To round 8, look at 1. Is it greater than 5? If the number is greater than 5, round the number up by 1. If the number is smaller than 5, the number remains the same.
What is the difference between a rounded number and an estimated one?
Estimating will frequently be the same as rounding, but not necessarily. Rounded numbers have specific rules about where they round to. These don't apply to estimation. 46 will always round up to 50, but it may be advantageous to estimate it at 45.
