Jay and Alex Decimal DLO 2013

The question that we am doing is about Decimals. We are going to have to add the decimal all up to get our answer. The question is that Andrew weighs 45.6kg and his cat weighs 4.8kg, so we have to add 45.6 and 4.8 together.

The strategy that we are going to use is rounding one of the decimal numbers to the nearest ten. First we will add 0.2 to 4.8 and then takeaway 0.2 from 45.6.So the question now will be 5 + 45.4 the reason that we took away 0.2 from 45.8 after adding 0.2 to 4.8 is to balance the numbers or there will be two much.

So now we will have to add 45.4 and 5 together.We know that 5 and 45 will add up to 50, then we just add the leftover 0.4 and the answer we got is 50.4
