Explain why we need to have a common denominator in order to add or subtract fractions.

Answer in paragraph form using complete sentences and include any calculations, graphs, and labeled diagrams as appropriate.

Answer

If you didn't it there wouldn't be an easy method to do the problem.Having the same denominator is the easiest method and is pretty basic.If you didn't have a common denominator such as:5/8 + 7/6, it would be virtually impossible to solve.

The table shows the relationship between the number of drops of food color added to different number of cups of cake frosting:


Cups of
Frosting Drops of
Food Color
2 6
3 9
4 12
Which point below shows an equivalent ratio in this situation?

A graph is shown. The title of the graph is Cake Decorating. The horizontal axis label is Frosting in cups. The horizontal axis values are 0, 10, 20, 30, 40, 50, 60. The vertical axis label is Food Color in drops. The vertical axis values are 0, 30, 60, 90, 120, 150, 180. Point C is plotted on the ordered pair 60,20, and Point M is plotted on the ordered pair 50, 150.

A. Point M, because if drops of food coloring are 50, then cups of frosting will be 150

B. Point M, because if cups of frosting are 50, then drops of food coloring will be 150

C. Point C, because if cups of frosting are 60, then drops of food coloring will be 20

D. Point C, because if drops of food coloring are 60, then cups of frosting will be 20

b) No, it is not a proportional relationship because the graph does not go through the
origin
c) Yes, it is a proportional relationship because the graph is a straight line
d) No, it is not a proportional relationship because the graph is not a straight line

A store is designing the space for rows of nested shopping carts. Each row has a starting cart that is 4 feet long, followed by the nested carts (so 0 nested carts means there's just the starting cart). The store measured a row of 13 nested carts to be 23.5 feet long, and a row of 18 nested carts to be 31 feet long.
How much does each nested cart add to the length of the row?


Each nested cart adds ----- feet to the length of the row.




If the store design allows for 43 feet for each row, how many total carts fit in a row?


----- total carts fit in a row.


Explain your reasoning for the total number of carts the store can fit in each row.
