Answer: 200cm long
Step-by-step explanation:
Let the length of the rod be x
red = 1/4 of the rod , which means 1/4 of x
orange = 2/5 of x
The remainder = x - (
+
)
= x - (
)
= 
yellow = 2/7 of the remainder , that is
yellow = 2/7 of
yellow = 
and it was given that the yellow section was 20cm long , that is
= 20cm
x = 20 x10
x = 200
Therefore the rod was 200cm long

Answer:
3 2/5 cups remaining
Step-by-step explanation:
To subtract fractions, they need a common denominator. I am using 5.
7 is equal to 35/5. Make 3-3/5 into an improper fraction of 18/5.
Now subtract: 35 - 18 = 17. There is 17/5 remaining.
Make it into a mixed number and you will get 3 2/5 remaining.
The correct answer is A. (1, 2)
Answer:
27 children
Step-by-step explanation:
For every 9 children, there are 4 adults. Those numbers added together equal 13. Now, if we divide the total number of adults and children by 13, we will get the number of how many groups there are of 9 kids and 4 adults.
39 / 13 = 3
There are 3 groups of 9 kids and 4 adults, which means to find the total number of children, we have to multiply 3 by 9.
3 * 9 = 27
Therefore, there are 27 children total. I know this was probably really confusing, but I hope it helped in some way! Have a lovely day!! :)
