The common mistake people make when adding fractions is to think you simply add the numerators and denominators together. This is wrong! For example, we know a half plus a quarter is 3 quarters but using that logic 12+14=2612+14=26 which is obviously
A mixed number is a combination of a whole number and a fractional part. For example 312312 is a mixed number. When adding or subtracting fractions and mixed numbers the most important part is to find a common denominator. This means getting the deno

Before we can add any fractions we must convert to a common denominator first. This is found by finding the first common multiple of 4 and 6 which is 12. If you don't find the first common multiple but instead use 24 or 36 etc you will still get to t

When adding mixed numbers you can make life easier for yourself by first adding the whole numbers together. In this case 2 + 3 = 5. Now we just
Now we just have to work out the remaining fraction sum 35+1235+12.
4 of 5
The common denominator of 35+1235+12 is 10. So we multiply the numerators and denominators of both fractions by 2 and 5 respectively. 3×25×2=6103×25×2=610 and 1×52×5=5101×52×5=510. Adding these together gives us 11101110.
Finally, remember to add on the 5 from the beginning of the questions to get 51110=611051110=6110.
