A 235
B 2.3 multiply 5
C 2.35
D 25 multiply 35

Answer 1

The answer is C.) 2.25

Explanation:

A is incorrect because when you multiply decimals, of course you can put the decimal aside for a while and multiply first which might be an easier way to multiply decimals, but you need to shift the decimal back after you’re done.

B is also incorrect because...yes it could be exponent but it’s not 2.3x5, it’s 4. 2.3x4.

D is incorrect too because 25x35 is 875, it’s not equivalent to 2.3x4 since 2.3x4 is 9.2.
