Jill walked #8 1/8# miles to a park and then #7 2/5# miles home. How many miles did she walk in all?
Okay, I think the easiest way to approach this problem is to first convert the mixed fractions to irregular fractions:
We want the total number of miles, so our equation is:
The LCD of 5 and 8 is 5*8=40, so:
Hope this helps!
In all she walked
We can do this a couple of ways.
Make improper fractions by multiplying the whole number by the denominator, then add the numerator (so for instance with the first mixed number, we'll have
Now we need to have the denominators be the same:
And now we divide it back out:
We can avoid the large numbers by adding the whole numbers first, then adding the fractions:
And now we add the fractions by finding a common denominator:
