Megan has 25 phone numbers stored in her cell phone. abby has some phone numbers stored in her cell phone. together they have a total of 61 phone numbers stored. if n = the number of phone numbers abby has stored in her cell phone, which mathematical sentence expresses the information above?

The total phone numbers stored in cell phones is the sum of phone numbers stored by Megan and that of Abby. The phone numbers should sum up to 61. The equation that would best show the situation is,
                                   25 + n = 61
If it is desired, we may solve for n and the answer is 36.

You can find the area of a rectangle by multiplying the length and height. so multiply 1/2*7/4(which is the simpler version of 1 3/4) and you get 7/8 as your answer.
