Tilly (11) and James (8) have been learning about equivalent fractions.

This is them in action!

Maths Crew

Equivalent Fractions have the same value, even though they may look different.

These fractions are really the same:

1     2     4
/  =  /  =  /
2     4     8

Why are they the same? Because when you multiply or divide both the top and bottom by the same number, the fraction keeps it's value.

The rule to remember is:

What you do to the top of the fraction
you must also do to the bottom of the fraction !

So, here is why those fractions are really the same:

  × 2   × 2  
1 = 2 = 4
/ / /
2 4 8
  × 2   × 2  
And visually it looks like this:

1/2   2/4   4/8
= =

Dear Tilly
I hope you know more about fractions than James does as he is only eight. I am glad you are being kept busy with school work, but I expect it is rather different.I am looking forward to Hog Hog getting home later today. Lots of love Bompa.
