1. Solving Exercise 1 - Math Workbook Grade 4 Volume 2 Page 41
Problem Statement:
Calculate:
Solution Method:

Answer:
2. Solving Exercise 2 - Math Workbook Grade 4 Volume 2 Page 41
Problem Statement:
Calculate:
Solution Method:
To subtract two fractions with different denominators, we first find a common denominator for both fractions, then subtract them.
Answer:
3. Solving Exercise 3 - Math Workbook Grade 4 Volume 2 Page 41
Problem Statement:
Calculate (by the denominator):
Solution Method:
Express the natural number as an appropriate fraction, then subtract the two fractions as usual.
a) What fraction of the garden area is used for growing cabbage and turnips combined?
b) By how many fractions of the garden area is the turnip cultivation greater than cabbage cultivation?
Solution Method:
a) Area for growing cabbage and turnips = area for growing cabbage + area for growing turnips.
b) The difference between the area for growing turnips and cabbage = area for growing turnips - area for growing cabbage.
Answer:
The area for growing cabbage and turnips is:
2/5 + 3/7 = 29/35 (garden area)
The excess area for growing turnips over cabbage is:
3/7 - 2/5 = 1/35 (garden area)
Answer: 29/35 garden area; 1/35 garden area
