He had 3/4 of a ball of twine. He bought 3 more balls of twine. How many balls of twine did he have altogeth?

I'm not sure but is it 3 and 3/4 balls of twine. Please help, thank you.

Yes.

To get the answer to this question, you need to add the amount of twine he already had with the amount of twine he bought.

He already had 3/4 of a ball of twine.

He bought 3 more balls of twine.

To add fractions, you need a common denominator. In this case, since the fraction is out of 4, we can convert 3 to a fraction with a denominator of 4.

3 as a fraction with a denominator of 4 is 3/1 * 4/4 = 12/4.

Now, we can add the fractions:

3/4 + 12/4 = 15/4.

This means he had a total of 15/4 balls of twine.

To simplify this fraction, we can divide the numerator and denominator by their greatest common divisor, which is 1 in this case:

15/4 รท 1/1 = (15/4) * (1/1) = 15/4.

So, the final answer is 15/4 balls of twine.
