Bobby subtracted 75 - 45 and said the answer is 30. Is his answer reasonable? why or why not?

It looks reasonable to me because 75-45= 30 and 30+45= 75

His answer is reasonable because

75-30=45 and 45+30=75.

It looks reasonable to me.

7 - 4 = 3
5 - 5 = 0

I don't understand the question.

Is the answer reasonable?
30 is the answer.

yea wut that nicole said

To determine if Bobby's answer of 30 is reasonable for the subtraction problem 75 - 45, you can perform the calculation yourself.

The subtraction operation is fairly straightforward - you subtract the second number (subtrahend) from the first number (minuend) to find the difference. So, in this case, you subtract 45 from 75.

To perform the calculation:

1. Start with the minuend, which is 75.
2. Subtract the subtrahend, which is 45.
3. The result is the difference between the two numbers.

Following these steps:

75 - 45 = 30

So, based on the calculation, Bobby's answer of 30 is indeed correct. Therefore, his answer is reasonable.
