All you need to know is that a km is 1000 m ( as the prefix kilo always means 1000 let it be even 1kg and that is equal to 1000g )
also know
that a 100 cm is 1 m and that's cause the prefix centi is 10^–2 (0.01)
answering your question
a) 5km = 5000m
5km and 20m in m is 5000m + 20m = 5020m
b) 13 cm = 13/100m = 0.13m
7m and 12cm is 7m + 0.13m = 7.13m.
remember
1km = 1000m
100cm = 1m

5 seashells , because 9 + 1 = 10 and if you were to give them an equally amount of seashells it would be 5 if you split 10 in half . SO the answer would be 5 .
It is either c or d
because when u are calculating you have to consider the flat fee and .25 miles per hour
im not sure what ur asking. but c is a line segment
It is given in the problem that out of 25 students in Hansels class 17 students went to the class trip to the zoo. From the above information it is easy to find the percentage of students that went for the class trip to the zoo.
Total number of students in the class = 25
Number of students that went for the class trip to the zoo = 17
Then
Percentage of students that went to the zoo = (17/25) * 100
= (17 * 4) percent
= 68 percent
So 68% of the students in Hansels class went for the class trip to the zoo.
