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

Estimating sumsUse rounded numbers to estimate sums.Example 1Give an estimate for the sum of 19.61 and 5.07 by rounding to the nearest tenth.Round each number to the nearest tenth.Example 2Estimate the sum of 19.61 + 5.07 by rounding to the nearest whole number.Round each number to a whole number.Estimating differencesUse rounded numbers to estimate differences.Example 3Give an estimate for the difference of 12.356 - 5.281 by rounding to the nearest whole number.Round each number to the nearest whole number.Now subtract.So 12.356 - 5.281 ≈ 7.Estimating productsUse rounded numbers to estimate products.Example 4Estimate the product of 4.7 × 5.9 by rounding to the nearest whole number.Round each number to a whole number.So 4.7 × 5.9 ≈ 30.Again, in decimals, as in whole numbers, if both multipliers end in .5, or are halfway numbers, rounding one number up and one number down will give you a better estimate of the product.Example 5Estimate the product of 7.5 × 8.5 by rounding to the nearest whole number.You can also round the first number down and the second number up and get this estimate.In either case, your approximation will be closer than it would be if you rounded both numbers up, which is the standard rule.Estimating quotientsUse rounded numbers to estimate quotients.Example 6Estimate the quotient of 27.49 ÷ 3.12 by rounding to the nearest whole number.Round each number to the nearest whole number.
First convert them t top-heavy fractions. Treat these as you would ordinary fractions: find common denominator and so on. At the end, convert the top heave fraction back to a mixed fraction.
When both of the fractions are not even mixed numbers!
I would not recommend estimating 1-digit numbers.
No, because then it would not be a mixed number.
No. They would then be mixed numbers, not integers.
Whole numbers such as 5129 are not normally expressed as mixed numbers
You can't. Mixed numbers are greater than one.
6.87 = 687/100
all the time but not when baby

you would convert the mixed numbers into fractions where the top number is greater than the bottom number, then multiply both the numerator and the denominator by a number that makes the denominators the same.
Convert them to improper fractions and proceed the same way you would multiply two fractions.
They Can Be used in many ways of such are the speed of a ball the score the speed of the player and his and many more
