WALT: Solve addition problems with tenths by changing one number into a whole number.
This week in maths we learnt about solving problems with fractions, decimals and percentages. One main thing I learnt was that when the question seems like a addition, it can be turned into a subtraction equation. For example: Jeff has 9.7 metres of rope. Brad has 8.6 metres of rope. What is the difference the between?
Some people may solve it like this: 8.6 + 0.4=9.0 9.0 + 0.7=9.7 0.4 + 0.7=1.1
How I solve it: 9.7 - 8.6=1.1
