Question 2.
Mr. Penman had $$\frac{2}{3}$$ liter of salt water. He used $$\frac{1}{5}$$ of a liter for an experiment. How much salt water does Mr. Penman have left?
Quantity of salt water = $$\frac{2}{3}$$
Quantity of salt water used = $$\frac{1}{5}$$
Quantity of salt water left = $$\frac{2}{3}$$ – $$\frac{1}{5}$$ = $$\frac{10}{15}$$ – $$\frac{3}{15}$$
= $$\frac{7}{15}$$ .

Question 3.
Sandra says that $$\frac{4}{7}$$ – $$\frac{1}{3}$$ = $$\frac{3}{4}$$ because all you have to do is subtract the numerators and subtract the denominators. Convince Sandra that she is wrong. You may draw a rectangular fraction model to support your thinking.
No, $$\frac{4}{7}$$ – $$\frac{1}{3}$$ = $$\frac{5}{21}$$ not $$\frac{3}{4}$$

Explanation :
$$\frac{4}{7}$$ – $$\frac{1}{3}$$ =Â $$\frac{12}{21}$$ – $$\frac{7}{21}$$ = Â $$\frac{5}{21}$$
no, first find the l.c.m of the denominators that is lcm of 7 and 3 is 21 . then multiply the denominators to make 21 and and also multiply same number with the numerator . then after making denominators equal subtract the numerators .

Question 3.
Robin used $$\frac{1}{4}$$ of a pound of butter to make a cake. Before she started, she had $$\frac{7}{8}$$ of a pound of butter. How much butter did Robin have when she was done baking? Give your answer as a fraction of a pound.
Quantity of butter used to make cake = $$\frac{1}{4}$$Â  pound
Quantity of butter with Robin before baking cake = $$\frac{7}{8}$$Â  pound .
Total Quantity of butter with Robin after baking = $$\frac{7}{8}$$Â  – $$\frac{1}{4}$$ poundÂ  = $$\frac{7}{8}$$Â  – $$\frac{2}{8}$$ = $$\frac{5}{8}$$ pound
Therefore, Robin have $$\frac{5}{8}$$ poundÂ  when she was done baking .
Katrina needs $$\frac{3}{5}$$ kilogram of flour for a recipe. Her mother has $$\frac{3}{7}$$ kilogram of flour in her pantry. Is this enough flour for the recipe? If not, how much more will she need?
Quantity of Flour Required for Recipe = $$\frac{3}{5}$$
Quantity of Flour with her mother = $$\frac{3}{7}$$
Quantity of Flour Enough or not = $$\frac{3}{7}$$ – $$\frac{3}{5}$$Â  = $$\frac{15}{35}$$ – $$\frac{21}{35}$$ = – $$\frac{6}{35}$$ that means negative indicate doenot enough.
She needs more $$\frac{6}{35}$$ Quantity of Flour for the Recipe .
