Ok so Danielle has to walked a total of 2 miles she has walked 1 1/4 of a mile already how many mile dose she have left .

Answer 1

Hi Abigail,

I hope I can help you understand this problem. To start, I encourage my students to draw a simple diagram of the problem to make sense of it. Here's an example

__________________________________

Danielle's total walk 2 miles

__________________________________

? what we don't know

_______________

1 1/4 miles that she

has already walked

_______________

So if we start with how much she's walked so far, 2 miles, and take away (subtract) what she has already walked, 1 1/4 miles we will know what she still needs to walk.

This will be our equation for this problem 2 - 1 1/4=?

There are many ways to solve subtraction problems with fractions, let's try turning 2 wholes into a fraction

2/1- 1 1/4. Now we need common denominators, so we will multiply the numerator and denominator of 2/1 both by 4 and our new equation will be 8/4-1 1/4. We are not ready to solve yet, since we need to turn 1 1/4 into an improper fraction, 5/4. Then we have 8/4-5/4=3/4 (we only subtract the numerators, the denominators remain the same). Our answer is 3/4 mile, always remember for word problems we need to include a unit in our answer.

Hope this helps, Abigail!

Answer 2

Ok so Danielle has to walked a total of 2 miles she has walked 1 1/4 of a mile already how many mile dose she have left .

To do this, you would do the problem 2-1 and 1/4. You could change each number into an improper fraction, so you would have 8/4-5/4. Then you can subtract the fractions, subtracting only the numerator (top number).

Answer 3

Could also do: 2 = 8/4 and 1 1/4 = 5/4, so 8/4 - 5/4 = 3/4

Answer 4

2 - (1 1/4)

1 + 1 - (1 1/4)

1 + 1 - 1 - 1/4

1 - 1/4

4 / 4 - 1 /3

3 / 4

or

2 - (1 1/4)

(8 / 4) - (5 / 4)

3 / 4
