Maths Homework
Hi folks, my daughter asked me for help with her maths homework but a few of the questions stumped me. I never was very good at maths myself, but I do know there are some very knowledgeable people on this forum so I'm asking for some help.
Q1. (Place Value) Suppose we were allowed to put more than a single digit in each place column. What are the different numbers that could be represented by 2134?
Q2. (Perimeter Possibilities) Using just whole numbers, how many rectangles can you draw that have a perimeter of 36 units? Is there a short way of finding out the number of rectangles you can draw with any even perimeter?
Q3. (The liquid Problem) Suppose you have a large vat of liquid.
(a) You have a 3lt measure and a 5lt measure. How can you take 1 litre from the vat?
(b) You have a 10lt measure and a 7lt measure. How can you take 9 litres of liquid from the vat?
Any help is greatly appreciated.
