say you estimate5.21 x 78.03 you can estimate by the whole number so the 5 stays the same and 78 turns to 80 so it should look like this 5x 80=400 ,so 5.21 x 78.03 =400. SO what i did was use the compatible numbers 5 and 80
It is most useful for finding quotients because it works with multiples.

estimate the highest place value 19x8?By Lewis Harvin
Its value will be reduced as the numbers of moles of the materials is reduced
Similar fractions. or decimals ending in repeating 9s - for example, 0.5 = 0.4999... or fractions and percentages eg 1/5 = 20% The answer cannot be numbers equal in absolute value but with opposite signs because although they have the same absolute value they do not have the same value - as required by the question.
The pH value is a measure of the acidity/basicity of a solution.
The best way to estimate a quotient using compatible numbers is to first understand how compatible numbers work. They are numbers that are close in value to the actual numbers and are easily added, subtracted or divided.
Value
What are compatible fractions? Round the whole number to the closest compatible number to the denominator. Compatible numbers are numbers that are close in value to the real number that would make it easier to find an estimate calculation. compatible numbers are numbers that are a like or can compared like fact families! Compatible numbers When estimating, compatible numbers are numbers that are close in value to the actual numbers, and which make it easy to do mental arithmetic. In mathematics, compatible numbers are the numbers that are easy to add, subtract, multiply, or divide mentally. Compatible numbers are close in value to the actual numbers that make estimating the answer and computing problems easier. We can round the numbers to the nearest ten, hundred, thousand or ten thousand to make them compatible numbers. For instance, if we have to add 493 and 549, we can make the numbers compatible by rounding them up to the nearest tens or hundreds. 490 and 550 (rounded to the nearest tens) or 500 and 500 (rounded to the nearest hundreds) are much easier to solve. So, we know the answer is about 1040 or 1000. Let us see some examples to understand how we can perform subtraction, multiplication and division using compatible numbers. Subtraction: Find the difference between 376.5 and 612.2 Here, we cannot find the difference between 376.5 and 612.2 easily as they are not compatible. So, we make the numbers compatible by rounding both the numbers to the nearest tens. Multiplication: Find the product of 24.3 and 18.7. It is difficult to find the product of 24.3 and 18.7 mentally and quickly. So, we use compatible numbers and find the which is closer to the actual answer. Division: Divide 856 by 33. To find the answer to 856 รท 33, will take us time as we need to divide to get the answer. However, if we make the numbers compatible, we can mentally find an answer close to the actual answer as shown. Fun Facts Compatible numbers help in simplifying the calculation of an estimate only.
Compatible numbers are numbers that are close in value to the actual numbers and easy to add, subtract, multiply, or divide mentally.So a logical compatible number for 77 would be 80.

If you replace variables in an expression by numbers (in case there are any variables) and then do the indicated operations, you get a number. That final number is the "value" of the expression.
