Flannery used 30 lilies and 78 roses to create six identical flower arrangements. Write an equation to describe the relationship
Volgvan

Number of lilies used= 30 lilies

Number of roses used= 78 roses

To make the six identical arrangements:

We need to divide lilies into six equal parts, as well as number of roses in six equal parts.

I=Number of lilies in each arrangement = \frac{30}{6}=5

r=Number of roses in each arrangement = \frac{78}{6}=13

Total number of flowers in arrangement (I + r)= 5 Lilies + 13 Roses=18 (Flowers)

The relationship between l, the number of lilies, and r, the number of roses:

→ 5 I = 13 r

I=\frac{13 r}{5} , r =\frac{5I}{13}
