Question

Alma has a 10-foot roll of wrapping paper. She cuts off 2 3/4 feet of paper to wrap a gift how much paper is left on the roll?

Answer 1

Step-by-step explanation

to solve this we need to do a subtraction, so

remainign paper= total paper- cut paper so

Step 1

Let

`\begin{gathered} \text{total paper= 10 ft} \\ \text{cut paper= 2 }(3)/(4) \end{gathered}`

so

a) convert the mixed into improper fraction,

remember:

`a(b)/(c)=((a\cdot c)+b)/(c)`

so

`2\text{ }(3)/(4)=((2\cdot4)+3)/(4)=(11)/(4)`

now, replace to solve

remainign paper= total paper- cut paper so

replace

`\begin{gathered} \text{remaining paper= 10-}(11)/(4) \\ \text{remaining paper= }(10\cdot4-1\cdot11)/(4)=(40-11)/(4)=(29)/(4) \end{gathered}`

so, the remainin paper is

`(29)/(4)\text{ ft}`

I hope this helps you
