Kelly subtracted 2.3 from 20 and got 17.7. Explain why this is reasonable.
This is reasonable because 20 - 2 = 18.
Think about it in terms of money. Your bill comes to $2.30. You give the clerk a $20 bill and she gives you $17 in bills plus some change.
It is reasonable because If you subtract 20 - 2 it is 18 and all it is doing is just adding a .3 to the 2 so it would just be subtracting 20 - 2.3 which is no difference and subtracting .3 more would give you the answer 17.7. hope that this gives you an A+ on your homework because I had this on my homework. My age is 10 and I run track,and actually I just won the JR. Olympics in Jacksonville, Florida.Also I was on the NEWS. My birthday is JAN.30,2005.I go to Deca-Prep.
maybe this will help you.
Im in the 5th grade. Im 11 years old.
The answer is reasonable because if you subtract 20-2 you would 18. and subtracting 20-2.3 is just subtracting .3 and your answer would be 17.7 in decimals. as a whole number it would be 17 7/10 or 100.
hope this will help you do your math homework because this site has helped me with my homework right now. thank you and hope someone will give me a thank you to help them with their homework.
20 - 2 = 18
Subtracting .3 more gives you 17.7.
I hope this helps. Thanks for asking.
