Makalyah wrote the number Two hundred fifty-six and forty-two hundredths as 256.042. Was she correct or did she make an error? If so, what was the error?

Incorrect. Proper 256.42

Step-by-step explanation:

The hundredths place is the second place after the decimal. The extra decimal made it read as two hundred fifty-six and forty-two thousandths

b) well because you get well

the mistake in the pattern is that :

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
