Week Eight - Friday 26th March

Today we learned about using ratios to split up amounts fairly. Note that fairly does not always mean in half!

e.g Split $150 in the ratio 3:7.
3+7=10. This will be the denominator (bottom number) for my fractions.
3/10 x 150 = $45. 7/10 x 150 = $105
Double check: $45 = $105 = $150

Homework: ex 6.03
Remember to bring your homework books on Monday as we will be using them to study for the test.

Reminder: ask your parents about interview times and grab one from me.
