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:

1/4 + 2/6

1/4 + 1/3

LCM is 12

(3×1 + 4×1)/12

7/12

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

the answer is b.)

< 1=< 2
