On day no 9, because to increase her mileage by 4 to reach 8 it will take her 4/0.5=8 days plus day 1 where she ran just 4 miles.

Kimane and a friend picked apples. Kimane picked 4 2/3 and his friend picked 5 5/6 pounds. About how many pound of apples do the
Gala2k [10]

Answer:

9\dfrac{1}{2}

Step-by-step explanation:

To find many more pounds of apples Kimane and his friend needs to get, we first need to find out how many pounds of apples they picked together.

Kimane = 4\dfrac{2}{3}

Friend = 5\dfrac{5}{6}

We add them together to find out how many pounds of apples they currently have.

Total Pounds = 4\dfrac{2}{3}+5\dfrac{5}{6}

Just to make the equation clearer, we separate the whole numbers from the fractions.

=4+5+\dfrac{2}{3}+\dfrac{5}{6}

=9+\dfrac{2}{3}+\dfrac{5}{6}

Now since we cannot add the 2 fractions directly since they have different denominators, we need to convert the /dfrac{2}{3} into a fraction with the same denominator.

We multiply both the numerator and denominator by 2 to have the same denominator.

\dfrac{2*2}{3*2}=\dfrac{4}{6}

So now we have:

=9+\dfrac{4}{6}+\dfrac{5}{6}

=9+\dfrac{9}{6}or1\dfrac{1}{2}

Total Pounds = 10\dfrac{1}{2}

Now that we know how many pounds Kimane and his friend collected, we simply subtract 20 and the total amount Kimane and his friend had already collected.

20-10\dfrac{1}{2}

=9\dfrac{1}{2}

So Kimane and his friend still need to get 9\dfrac{1}{2} more pounds of apples to get 20 pounds of apples.
