A florist arranges 4 flower arrangements in 92 minutes.
Black_prince [1.1K]

Answer:

\boxed {\boxed {\sf 9 \ arrangements }}

Step-by-step explanation:

Let's set up a proportion using the following setup:

\frac{arrangements}{minutes} =\frac{arrangements}{minutes}

We know that the florist can arrange 4 in 92 minutes.

\frac{4 \ arrangements}{92 \ minutes} = \frac{arrangements}{minutes}

We don't know how many the florist can arrange in 207 minutes, so we say x arrangements can be completed in 207 minutes.

\frac{4 \ arrangements}{92 \ minutes} = \frac{ x \ arrangements}{ 207 \ minutes}

\frac{4}{92} =\frac{x}{207}

Solve for x by isolating it on one side of the proportion.

x is being divided by 207. The inverse of division is multiplication. Multiply both sides of the proportion by 207.

207*\frac{4}{92}=\frac{x}{207}*207

207*\frac{4}{92}=x

207*0.0434782609=x

9=x

The florist can arrange <u>9 arrangements</u> in 207 minutes.
