You simply need to read and reread our fun questions designed in a simple language for fast understanding. In most problems we work, we will be approximating a solution, because we will not have perfect information. Presents Age 3 to 5 Comparing the wrapped presents in this activity will give children the chance to explore and discuss weight, including the idea that large objects aren't necessarily the heaviest. It is often easier to solve a problem in small steps, rather than trying to find a way to jump directly from the given information to the solution. It is a well-known fact that NFL football fields are 120 yards long. Create your account, 9 chapters | Of course, this cost estimate assumes that there is no waste, which is rarely the case. When using estimation in a problem solving context, there are important things to keep in mind. In this case, we can use estimation to find an approximate distance from Sally's to Eric's. Again, we recognize the weight placed on 84%, making the answer higher than 79.5. But, if it is an estimate, you show it by using a symbol that is also only close to but not exactly the equal sign. If gas in your area averages about $3.50 per gallon, we can use that to find the running cost: Sonata:[latex]\displaystyle{460.7}\text{ gallons}\cdot\frac{\$3.50}{\text{gallon}}=\$1612.45[/latex], Hybrid: [latex]\displaystyle{332.1}\text{ gallons}\cdot\frac{\$3.50}{\text{gallon}}=\$1162.35[/latex]. Your estimate is somewhere between .40 and .45. As you walk around see how good you are at estimating answers before they come up. Well, you can estimate the times.
