MATHS MATE TERM 3 SHEET 8

Predict: I predict that this question is going to be about working backwards.

Read: I think of a number,multiply it by4 and the  divide by 3. If the result is 12, what was the original number?

Clarify: I had nothing to clarify

The Big Question: What was the original number?

mathematicians toolbox: I used the strategy of working backwards.

Solution: First thing I do is change all the operations into their invert operation. So if I work backwards I multiply by 3 which gives me 36. Then I divided that by 4 which gave me 9, so that was my answer.

Conclusion: In conclusion I used the strategy of working backwards to get an answer of 9.
