Question

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

Answer 1

a) 5/12×3=1 1/4 I know this for sure

Answer 2

Given, each member of the group completed
`(5)/(12)` 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
`(5)/(12)`

So height of the tower =
`((5)/(12)) (3)`

=
`((5)(3))/(12)`

=
`(15)/(12)`

Now to find the height we have to simplify
`(15)/(12)`.

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,
`(5)/(4)`.

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

`(5)/(4) = 1 (1)/(4)`

So we have got the required answer.

Option A is correct.
