Danielle ran 3 1/8 miles on tuesday and 4 and 1/2 miles on wednesday and 5 1/4 miles on thursday how far did danielle run all together this

Well you would figure out a common denominator for all fractions.

3 1/8

4 1/2

5 1/4

the common denominator would be 8. so multiply all the fractions by the number that would give you 8 on the bottom of the fraction

1/8 x 1 = 1/8

1/2 x 4 = 4/8

1/4 x 2 = 2/8

now you would set up your problem

3 1/8 + 4 4/8 + 5 2/8

first add the fractions

1/8 + 4/8 + 2/8 = 7/8

then add the whole numbers

3 + 4 + 5 = 12

now put the number and fractions together and you have your answer

12 and 7/8
