aira needs 1/4 cup ice cream and 2/3 cup root beer to make a rootbeer float. she is using one measuring cup. how can she write 1/4 and ⅔ as a pair of fractions with a common denominator to fond out which measure cup to use

11/12

the height of the surface increases from the center out to the sides of the road.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
