Question

Madison planted her garden with 2 5 marigolds and 3 7 tulips. What fraction of the plants in the garden are either marigolds or tulips?

Answer 1

To answer this you will combine both fractions together to get a total. The denominators are not the same so you will need to create equivalent fractions for both with a common denominator. The denominator is like the units, and to be able to add them they must be the same.

2/5 + 3/7

2/5 = 14/35 and 3/7 = 15/35

14/35 + 15/35 = 29/35

29/35 of the garden are these 2 flowers.

Answer 2

Answer:

$\frac{29}{35}$

Step-by-step explanation:

We have been given that Madison planted her garden with $\frac{2}{5}$ marigolds and $\frac{3}{7}$ tulips.

To find the number of plants in the garden that are either marigolds or tulips, we will add both numbers as:

$\frac{2}{5}+\frac{3}{7}$

Make a common denominator:

$\frac{2\cdot 7}{5\cdot 7}+\frac{3\cdot 5}{7\cdot 5}$

$\frac{14}{35}+\frac{15}{35}$

Add numerators:

$\frac{14+15}{35}$

$\frac{29}{35}$

Therefore, $\frac{29}{35}$ of the plants in the garden are either marigolds or tulips.
