You should used it in a number line
3 1/3+2 1/7=
They can be: 7 and 1/2 or 7 and 3/6
To add mixed numbers and whole numbers, you simply treat the mixed numbers like they are whole numbers (4 3/4) turns to (4), then add the regular whole number, say, 7, and then re-add the fraction. For example, if you were adding 4 3/4 and 7, you would change 4 3/4 to 4, add 7 to get 11, then add the 3/4 back in, to give you 11 3/4.
7 7/12 plus 3 8/9
3 and 21/30 = 3 and 7/10
50/7 as a mixed number is 7 and 1/7
How to Solve 7 1/2 + 5 3/4= Make Both Mixed Numbers Do your normal Fraction Addition Make It into a not Mixed fraction
Any two mixed numbers such that their whole number is 1 and the sum of the fractional parts is 1, eg: 1 1/4 + 1 3/4 1 1/3 + 1 2/3 1 3/7 + 1 4/7
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.
It is: 4 and 3/7 as a mixed number
You can either subtract the whole number portions, then subtract the numerators, or you can convert the mixed numbers to improper fractions, subtract the numerators, and simplify. For example, 3 5/7 - 2 1/7 can be handled as 3 - 2 and 5/7 - 1/7, or as 26/7 - 15/7; either way, it's 1 4/7.
Whole numbers can't be mixed numbers.
