Melissa said that each member of her group completed 5/12 foot of a tower for a garden display. There were 3 members in her group. Which equation shows the total height of the tower, in feet, when the members stacked all parts on top of each other?
A) 5/12 x 3 = 1 1/4
B) 5/12 ÷ 3 = 5/36
C) 3 + 5/12 = 3 5/12
D) 3 - 5/12 = 2 7/12

a) 5/12×3=1 1/4 I know this for sure

Given, each member of the group completed [tex] \frac{5}{12} [/tex] foot of a tower for garden display.

There were 3 members in the group. We have to find total height of the tower.

To find total height of the tower we will multiply number of members with [tex] \frac{5}{12} [/tex]

So height of the tower = [tex] (\frac{5}{12}) (3) [/tex]

= [tex] \frac{(5)(3)}{12} [/tex]

= [tex] \frac{15}{12} [/tex]

Now to find the height we have to simplify [tex] \frac{15}{12} [/tex].

To simplify it we will divide the numerator and denominator by a common factor of them. Common factor of 15 and 12 is 3. If we divide both of them by 3 we will get, [tex] \frac{5}{4} [/tex].

We have got an improper fraction. We need to convert it to mixed fraction.

[tex] \frac{5}{4} = 1 \frac{1}{4} [/tex]

So we have got the required answer.

Option A is correct.
