Maths Mate S6 Q22 T4

Predict: I predict that this question will be about  money and multiplication.

Read: Which deal cost less per metre? A) $1.50 for 15 metres B) $5.00 for 45 metres

Clarify: I had nothing to clarify in this question.

Mathematician’s toolbox: The strategy I used from the mathematician’s toolbox was to work backwards

Big question: The big question is what deal costs less per metre

Solve: First, I multiplied 15 by 3, because that then equalled 45. Then, because I had multiplied 15 metres by 3, I multiplied the price, $1.50 by 3. That was $4.50, so it was less than deal B, $5 for 45 metres, and therefore better value.

Summary: It might been hard until you figure it out, so good luck
😉

Maths Mate S3 Q23 T4

Predict: I predict that this question will be about addition.

Read: Fill in the magic square. [Hint: Every row, column and diagonal has the same sum.

Clarify: I had nothing to clarify in this question.

Mathematician’s Toolbox: The strategy I used from the mathematician’s toolbox was prior knowledge.

Big question: The big question is what are the missing numbers in the magic square.

Solve: Firstly, I worked out that all the numbers that were in a row made 18, and those numbers were 8, 6 and 4. Next to the 8 there was 7, so I added 3 to make 18. After that, it was easy going because I knew basic addition.

Summary: This problem was quite easy to solve if you knew basic addition of numbers.
