Halen wrote the product 0.4 for the problem at the right. Don says that is not correct because when you multiply tenths by tenths, the product will be in the hundredths. Is Don right? Explain.

Helen is correct and Don is wrong

Step-by-step explanation:

Halen wrote the prodect 0.4 for the problem .5×.8. Don says that is not correct since when you multiply tenths by tenths the product will be in the hundreths. Is Don right?

.5 × .8 = 0.4

Helen is correct

Don is wrong because the zero(0) at the end of decimals are usually ignored

Such as: 0.10 ; it is usually written as 0.1

Same thing goes for 0.40 which is written as 0.4

Therefore, Helen is correct and Don is wrong
