Just wondering if anyone can explain to me please how to multiply decimals.
have seen lots of questions in Bond Assessment papers where it says e.g What's 0.1 x 0.1 or what's 0.2 x 0.1 or similar
Can anyone help please?
Not sure if this is the "official" way taught in schools, but the way I think of multiplying decimals in my head is as follows.
Firstly remember that the actual numbers in the answer will be the same as for an equivalent non-decimal multiplication (e.g. 2 x 1). Its just the decimal point that you have to make sure is in the right place.
Take your example 0.1 x 0.1.
0.1 x 1 = 0.1 (obviously)
So 0.1 x 0.1 will be 10 times smaller = 0.01.
Similarly 0.2 x 0.1 = 0.02.
Or for a slightly harder example, 0.7 x 0.005.
0.7 x 5 = 3.5
0.7 x 0.005 = 0.0035
