Students will need to understand that the term “parts” refers to equal amounts. In the first question, the amounts are measured by volume or capacity, that is, 100 mL of water must be mixed with the same volume of salt and three times that volume of flour.
Note that 1 mL equals 1 cm3, often written as 1 cc. Students will need access to flour, salt, and water. Ensure that they organise the correct amounts before they are mixed.
The above diagram is also useful for students attempting question 2.
Since Jessie has doubled the amount of flour, she must also double the amount of salt, that is, 2 parts salt : 6 parts flour.
Question 3 asks students to relate fractions to turns of the minute hand of a clock face. Previous experience with folding paper circles is very useful here (see the activities on page 17).
