Decimals; help please!

[i need help !!]

HELP ME Answer these questions and explain how you got the answers:D 0.6 - 0.22 =

i have more questions 0.5 - 0.12 =

0.7 - 0.36 =

0.9 - 0.15 =

[Temperal]

Multiply everything by 100.

60-22=38

Then, divide the answer by 100.
0.38

Do the others by yourself.

Of course, you don't have to do this, but you probably will have trouble otherwise.

[i need help !!]

0.5 is now 0.50 amd 0.12 is 0.12 - 0.38 !! YAY !! TY YOUR the best !!

w00t w00t

[Temperal]

Huh? Wait, no.

0.5 times 100 is 50.

0.12 times 100 is 12.

If you have 0.5-0.12,
you then get 50-12.
Then, once you do the minusing (bad grammar), you get 38.
38 divided by 100 is 0.38.

Get it?

You don't need to multiply by a 100, just line up the decimals, and subtract regularly. Just drop the decimal to the correct space in the answer.

It would make it easier for her (him?), somedude!
Remember back in second and third grade when you were probably learning this stuff?

[Sillysidley]

Uh, I don't think I could multiply by 100 in 2nd grade...

[Temperal]

All you have to do is move the decimal point! I learned that in first grade!

By the way, read my private message!

ever heard of a calculator

[Temperal]

How about this:

In a-b, where a is a one digit decimal and b is a multiple digit one, tack a few zeroes onto a until it has the same number [of digits] as b.
