Question

A tree is 91 inches tall. How tall is it in feet and inches?

Answer 1

Hint: Let us find the relation between inches and feet. 1 foot is equal to 12 inches. Based on this relation, we can find the height of the tree in feet and inches. For that, we will divide tree height by 12 inches.

Complete step-by-step answer:
Here, we have to convert the height of the tree from inches into feet and inches.
As we already know that 12 inches = 1 foot.
Therefore, to convert 91 inches into feet and inches, divide 91 by 12.
$ \Rightarrow \dfrac{{91}}{{12}}$
Let us divide the above step.
The answer will be,
$ \Rightarrow 7\dfrac{7}{{12}}$
That is equal to 7 feet 7 inches.

Hence, the tree is 7 feet 7 inches tall.

Note:
The use of a unit depends on the situation, such as the area of a room is expressed in meters but the length of a pencil is expressed in centimetres and its thickness in millimetres. Thus, we need to convert one unit to another. Therefore, let us understand the relationship between units.
Let us know about some other standard conversions:
> 1 inch is equal to exactly 2.54 centimetres.
> 1 yard is equal to 36 inches.
> 1 foot is equal to 0.3048 meters.
> 1 meter is equal to 100 centimetres.
> 1 centimetre is equal to 10 millimetres.
> 1 kilometre is equal to 1000 meter.
Points to remember while converting units:
> To convert a bigger unit to a smaller unit, we have to apply multiplication.
> To convert a smaller unit to a bigger unit, we have to apply division.
