Answer:

22 strips.

Step-by-step explanation:

In order to solve this you just have to divide the total inches of paper that she actually has by the size of the strips that she´s going to make:

9 inches/2/5\\\frac{ 9inches}{\frac{2}{5} } \\\frac{45}{2}\\22\frac{1}{2}

So as you can see she can make a total of 22 strips and a half, but the half won´t be useful so she can make 22 strips.

First off it would be 9 divided by 2/5.
Then by using the reciprocal, multiply them both (change 9 to 9/1)

9/1 x 5/5 = 45/2

If you would like to convert it, it would be 22 1/2

A teacher is four time as old as a student .in 20 years, the student 's age will be half of the teacher 's age. How old are they
notka56 [123]
Let the present age of student be x
Present of teacher will be 4x

After 20 years,
Age of student = x + 20
Age of teacher = 4x + 20

According to the given condition after 20 years,
x + 20 = (4x + 20)/2
x + 20 = 2x + 10
2x - x = 20 - 10
x = 10

So student's present age is 10 years while teacher's is 4 x 10 i.e 40 years.
