Problems involving the addition and subtraction of unlike fractions.
Adding and subtracting fractions.Problems involving the addition or subtraction of unlike fractions
Addition and subtraction are inverse operations. So you can solve addition by subtracting.
By using division, multiplication, addition or subtraction
In order to add and subtract fractions with unlike denominators, it is necessary to convert them to equivalent fractions with a common denominator. Example: 1/4 + 1/6 The LCM of 4 and 6 is 12. 1/4 = 3/12 1/6 = 2/12
To complete an addition pattern using 3, you can rearrange the addition statements by using subtraction. For example, if the pattern is 3, 6, 9, you can see that each number increases by 3. To find the previous number in the sequence, you can subtract 3 from the current number: 9 - 3 = 6 and 6 - 3 = 3. This shows that subtraction can help identify the consistent step in an addition pattern.
