1) Marlene's ratio of phone calls to text messages is 3to 5. If she makes 27 phone calls, how many textsdoes she send?

Sagot :

Answer:

She sends 45 texts.

Step-by-step explanation:

This question can be solved using a rule of three.

For 3 phone calls, she sends 5 text messages. For 27 phone calls, how many texts?

3 phone calls - 5 texts

27 phone calls - x texts

3x = 5*27

x = (5*27)/3

x = 5*9

x = 45

She sends 45 texts.
