Question

Explain how to use estimation to help find the product of two decimals. Give an example with both estimated and actual answers. ??????

I dont know what to do??

Answer 1

2.235 is the answer to this

Answer 2

if you multiply decimals , the estimate value is necessary !

it could be understood easily, if at any place the number exceeds 4 , then the value in front is raised by one !

as;
2.234 = 2.23 , it will remain same but,
2.235 = 2.24 the 3 raised to 5 !!

if you have any problem yet , comment !!
