3/7 = 9/x
cross multiply because thats how u solve proportions
(3)(x) = (7)(9)
3x = 63
x = 63/3
x = 21
and if u will notice : 3/7 and 9/21 ....9/21 reduces to 3/7....so these are equivalent fractions...because proportions are nothing but equivalent fractions
Answer:
mean = 0.76
median = 0.75
range = 1.79
Step-by-step explanation:
mean = sum/no of items
for media they need to be sorted: 0.05,0.06,0.75,1.10,1.84
median is the middle item, so 0.75
range = largest item - smallest item = 1.84 - 0.05 = 1.79
Hello.
To find the percentage of how many students went on the field trip, we simply divide 18 by 25.
18/25 = 0.72
Convert decimal into fraction.
0.72 = 72%
Thus, 18 out of 25 students = 72% of students who are going on the field trip.
You're welcome.
