In the same way as you estimate them for whole numbers.

The basic idea is the same as when you estimate sums and differences of larger numbers (which may or may not be integers). You round the numbers to one or two decimal digits, then add them up.

it would not be a good time to estimate mixed numbers is when both of the fractions are not a mixed number

When doing sums with mixed numbers, it is often easier to convert the mixed numbers to improper fractions, do the sum and convert any resulting improper fraction back to a mixed number. This is especially true of division, but with subtraction, if the fraction part of the second mixed number is larger than the fraction part of the first mixed number (subtracting the second from the first), this will result in requiring borrowing from the whole number of the first mixed number. Using improper fractions avoids this complication and makes all sums easier.

you can make at least 25 sums

Convert them to improper fractions and proceed.

To divide decimals the partial sums method requires that numbers are separated into individual portions. The separated numbers are then solved in long division until eliminated.

Mixed numbers have fractional parts that must be compared; whole numbers do not.

Mixed number are rational numbers because they both have a whole number.

Infinitely many. 12+11, 13+10, 14+9, ... , 22+1, 23+0, 24+(-1), 25+(-2), ... and then you have sums with numbers to one decimal place (dp) such as 11.6+11.4, and so on. Not forgetting numbers to 2 dp, 3, dp, 4, dp, ... , infinitely many dp. But these are only sums of two numbers. There are sums of 3 numbers, 4 numbers, ... infinitely many.

Whole numbers such as 219 are not normally expressed as mixed numbers

Mixed numbers is when you have whole numbers and fraction.10 1/4 is a mixed number, the fraction equivalent is 11/4 and decimal equivalent is 10.25. Please note that mixed numbers is considered bad math practice.

to estimate with mixed numbers, round the numbers to the nearest whole number. example 3,1/3+1,1/2+1,3/4=7 you would round 3 in 1/3 to a 3 and the 1 in 1/2 to a 2 and then the 1 in 3/4 to a 2 which equals 7 total.

No.
