Need help on this question too hard :((

2/3

Step-by-step explanation:

Convert the fractions to decimals.

2/3 = 0.666

4/5 = 0.8

14/18 = 0.777

34/50 = 0.68

From the decimals, 0.666 is the only option which falls between 0.5 and 0.75.

625

Step-by-step explanation:

Since two slices is 250 calories, let us find how many calories is there in one.

250/2=125 (note, slash signs represents divide sign. When writing down, please write the actual sign.)

Now, we find how many calories are there in 5 pizza slices.

125x5=625
