The answer is:
She still needs to ride
From the statement, we know that Nance's friend is 4 1/2 miles away and she only has ridden 2 3/5 miles.
So, let be "x" the distance that she still need to ride to get to her friend's house.
The equation will be:
Remember that:
Also, if we need to add/substract fractions we must remember that:
If we need to switch fractions to mixed numbers, we need to:
- Perform the division
- Keep the whole number and make a fraction with the aproximated next whole number (remainder) as numerator, and the original denominator. We need to use the remainder to approximate to the next whole number.
Where:
So,
Then, substituting the given information into the equation, we have:
So, she still need to ride
or
To prove if the answer is reasoable, let's substituite the obtained value into the equation and check if the equation is satisfied:
Have a nice day!
