Solving Fraction Problems

WALT: Order fractions with different denominators.

This week in maths, we learnt about fractions. We learnt how to find out which fraction is larger with different denominators. When I first started I had a bit of trouble finding the right way to solve the questions. Once I had a bit of help, I got the answers straight away. This is our strategy... 

Which fraction is bigger, 6/8 or 3/5. First we multiply the denominators to get the whole number(denominator). Like this:

5 x 8=40

Next we divide the 40 by the denominators by the original denominators. Like this:

40 / 5=8

40 / 8=5

Finally we multiply these numbers by the original numerators. Like this:

8 x 3=24

5 x 6=30

So in the end it should look like this.

30/40 > 24/40.  

Solving Problems with Decimals, Fractions and Percentages

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
