The worksheets on this page have various types of practice for multiplying fractions. Included are problems that focus on cross-cancelling which is a skill that greatly simplifies the process of reducing fractions in the answer step. Cross cancelling prior to multiplying fractions results in much smaller products which are significantly easier to reduce and turn into proper fractions.
The steps for subtracting fractions is well illustrated in the fraction calculator at the link below. That page has a more detailed discussion of common denominators, mixed fractions and other topics that may help understand the steps necessary to subtract fractions.
As well as a printed blank hundred square, another way to visualise decimals is to make a decimal stick. Get a cane or long stick, place with tape a number 1 to the right hand end, then a 0 to the left. Ask them now to place 0.5 in the middle, then together work out where all the other decimal points should go.
We often talk of dividing as being the reverse of multiplying, and indeed when dividing fractions this is the case. The way you divide fractions is very similar to the way fractions are multiplied with a simple twist in the middle.
