Answer:
1. (a) 3/18 (b) 14/50 (c) 18/30
For the first 3 questions, its quite simple, you just subtract the numerators, and keep the denominator the same:
1. 7/18 - 4/18 = 3/18
2. 33/5 - 19/50 = 14/50
3. 24/30 - 6/30 = 18/30
For the next question, first we have to simplify the denominator of both fractions, and then subtract.
For Question A, we have 5/6 - 3/7, so we have to find the LCM of 6 and 7, which is 42.
So, we have to multiply the denominators to get them to 42
5/6 * 7/7 = 35/42
3/7 * 6/6 = 18/42
Now that they are like fractions, we can subtract directly
35/42 - 18/42 = 17/42
17/42 cannot be simplified further. That is our answer.
For (B) and (C), i'll just write the answers since the explanation is the same as (A)
B) 3/2 (Or 1 1/2 if they want it in the form of a mixed fraction)
C) 1/3
For the nexty question, we have to convert the mixed to an improper fraction, and then do the same steps as above:
6 2/3 and 2 5/6
To do this, we multiply the whole number by its respective denominator and add the product to the numerator, like so:
2 + (6×3)/3 = (2+18)/3 = 20/3
5 + (2×6)/6 = (5 + 12)/6 = 17/6
Now, we bring them both to the same denominator
20/3 × 2/2 = 40/6
17/6 × 1/1 = 17/6
Now, finally, we can subtract:
40/6 - 17/6 = 23/6
B) 8 7/12 - 4 3/4
= 103/12 - 19/4
= 103/12 - 57/12
= 46/12
= 23/6
Hope this helped!
