Answer: 48 text messages to his friend, Bianca

Answer 2

Answer:

The answer is

→ 48 text messages

Step-by-step explanation:

Were being asked how many text messages are to Bianca. Today, were using 3 ways on how to solve this problem. 2 are incorrect and 1 is correct.

First, let's use addition.

$120+\frac{4}{5} +\frac{1}{2} =121.3$

Were not looking for 121.3, it's too high. Therefore, using addition is incorrect.

Second, let's use subtraction..

$120-\frac{4}{5} -\frac{1}{2} =118.7$

Were not looking for 118.7 either. Therefore, using subtraction is incorrect as well.

Third, let's use multiplication...

$120 * \frac{4}{5} * \frac{1}{2} = 48$

As a result we got 48. Which is the answer your looking for.

Hope this helped! :^)
