The line plot below shows the heights of flowers in a garden. How much taller is the tallest flower than the shortest flower?​
Marat540 [252]

Answer:

1 3/4 inches

Step-by-step explanation:

<u><em>Given:</em></u>

<em>The line plot below shows the heights of flowers in a garden. </em>

<u><em>To Find:</em></u>

<em>How much taller is the tallest flower than the shortest flower?​</em>

<u><em>Solve:</em></u>

<em>Knowing that each dot represent it's heights.</em>

<em>Let's makes a table:</em>

<em>6 1/2 ⇒ О О</em>

<em>6 3/4 ⇒ О</em>

<em>7 ⇒ ОООО</em>

<em>7 1/4 ⇒ ОООООО</em>

<em>7 1/2 ⇒ ОООО</em>

<em>7 3/4 ⇒ ОО</em>

<em>8 ⇒ none</em>

<em>8 1/4 ⇒ О</em>

<em>8 1/2 ⇒ none</em>

<em>It's also given that the tallest flower and the shortest flower.</em>

<em>Which is:</em>

<em>Smallest → 6 1/2</em>

<em>Tallest → 8 1/4</em>

<em>Now all we have to do is subtract tallest flower from the shortest flower.</em>

<em>8 1/4 - 6 1/2</em>

<em>Break off 1 from 8 : 8 1/4 = 7 5/4</em>

<em>Now we have:</em>

<em>7 5/4 - 6 1/2</em>

<em>Subtract whole number: 7 - 6 = 1</em>

<em>Combine fraction:</em>

<em>5/4 - 1/2 = 3/4</em>

<em>1 + 3/4 </em>

<em>= 1 3/4 inches</em>

<em>Hence, the answer is [B] 1 3/4</em>
