A man uses his mobile phones for calls and messages in the ratio of 5:7 what is the percentage of its
calls?
Answer: 41.67%
How to solve:
ratio of calls and messages = 5 : 7
sum of the ratio = 5 + 7 = 12
percentage of calls = ( 5 / 12 ) × 100
=41.67%

6 270
Find the constant of proportionality.
Use the constant of proportionality to write a unit rate for the data in the table.
Write an equation to represent the relationship between time, t, and distance, d.
Answer: Constant of proportionality is 45 miles per hour.
Step-by-step explanation: To find the constant of proportionality you need to do miles/hours. It is always easier to do the first one as it is the smallest and thus eliminates the need to do harder problems.
miles/hours
90/2 = 45
135/3=45
225/5=45 and so on...
