Question

the number of text messages sent by Tiffany to the number of text messages sent by her brother is 3 to 4. Tiffany sent 12 text messages. How many text messages did her brother send?

Answer 1

To find out how many text messages Tiffany's brother sent, we use the ratio of messages sent by Tiffany to her brother (3:4). Tiffany sent 12 messages; therefore, her brother sent 16 messages after setting up a proportion and solving for the unknown number.

Step-by-step explanation:

The number of text messages sent by Tiffany compared to her brother is in the ratio of 3:4. Tiffany sent 12 text messages. To find out how many messages Tiffany's brother sent, we can set up a proportion where 3 corresponds to Tiffany's 12 messages, and 4 will correspond to her brother's number of messages, which we can call x. The proportion is:

3/4 = 12/x

By cross-multiplying to solve for x, we get:

3x = 4 × 12

3x = 48

x = 48/3

x = 16

So, Tiffany's brother sent 16 text messages.

Answer 2

16

Step-by-step explanation

12/3 = 4

4 x 4 = 16
