Answer:
first get the total ratio; 2 + 5 = 7
so the fraction of blue marbles is 5/7
then assume the number of total marbles to be k
then use the expression;
5/7*k = 65
7*5/7 * k = 65*7
5k =455
5/5k = 455/5
k = 91
then calculate the number if red marbles from;
x = 2/7*91
x = 26
Therefore there are 26 red marbles.
Answer:
A,D,E,F
Step-by-step explanation:
Length of the original ribbon = 2/3 yard
Length of the ribbon in which the actual ribbon has to be cut = 1/12 yards
The above information's are already given in the question. It is required to find the number of pieces that the ribbon can be cut with the length that is already mentioned.
Then
Number of pieces that will be there = (2/3)/(1/12)
= (2 * 12)/3
= 24/3
= 8
So the actual ribbon can be cut into 8 pieces and each piece will have a length of 1/12 yards. Hopefully the procedure for doing this problem is clear to you. this is the easiest method for attempting these kind of problems.
Answer:
1/4 + 1/4 + 1/4 or 1/8 +1/8 +1/8 +1/8 +1/8 +1/8
Step-by-step explanation:
To decompose a fraction simply means to take it apart. The most basic way to decompose a fraction is to break into unit fractions, which is when the numerator (top number) is 1. We can see that 6/8 is the same as the unit fraction 1/8 six times.
