Equivalent Decimals



Decimals are nothing but a whole numbers but broken into pieces, so example we have one whole block, and we cut it in 2 pieces, and we call it as Tenths. How to do equivalent decimals, so how do we write it ? We write it as 1 .2 tenth (Here decimal represents AND). But if we break that down even further into more ten pieces and take out and add 3 then we call these as Hundredths.  So this way we have once, tenths and hundredths. So this way we will write it as 1.13 (one and thirteenth, remember here the last piece that we saw. Here we will name the last 1 and 3 as thirteenth, the last digit even if it is zero we call it that). Now late us take one more piece of cube and break it down into ten equal parts that will be called as thousands. So we have ones, tens, hundredths and thousands. Let us say we have this number up in broken to two pieces .we will call it as 1.232 that is one and two thirty two thousands, so we read the decimal like this way.

Now moving up to equivalent decimals examples, what if we have only one block so we will call it as 0.1( here we will read it as zero and one tenth.) but let us say we want to turn it to hundredths. The whole one piece when broken into ten equal parts has the same value for 0.1 as well. However they are hundredth. so all we need to say hundredth we need to add a zero. Because when we read decimals we need to say the last digit. Thus it will be 0.10(we call it as zero and one tenth one hundredth.) so one tenth is equal to tenth hundredths.

How to find equivalent decimals? We can by taking the denominator and dividing it with the numerator of the same fraction. Now for example we have ½ as a fraction so, 2 have to get divided by 1 so we will add a zero and bring up a decimal point. This way we have 10 which will be divisible by 10. As 2 times 5 is equals to 10.  And 10 subtracted by 10 and remainder comes to zero. So we have got the solution as 0.5 is the equivalent decimal.
What is a Equivalent decimal are nothing but the decimals which have the equal proportions.
