Comparing different fractions: Which one should I choose?

So, you already know a fair few strategies for comparing the size of fractions with different denominators:
- Draw it
- Ask whether each fraction is more or less than half
- Converting the fraction to a decimal using short division

Here's a new method for when the fractions are VERY close and which can sometimes be quicker than converting to decimals:

Try it out on these equations: Write a problem to represent each of these equations as you solve it:

3/4 + 6/8

2/5 + 8/9

2/3 - 12/30

6/8 + 10/14
