Robert rode his bike 1/4 mile on Friday and 2/6 of a mile on Saturday. How far did he bike in all?

7/12 of a mile

Step-by-step explanation:

So to find the answer of this problem you have to add up both of the distances

1/4+2/6

2/6 can be simplified to 1/3

1/4+1/3

The denominator of this would be 12, so

3/12+4/12=7/12

this means he rode his bike 7/12 of a mile

7/12 of a mile

Step-by-step explanation:

1/4 + 2/6

1/4 + 1/3

LCM is 12

(3*1 + 4*1) / 12

7/12
