Answer:
John
Step-by-step explanation:
To be able to compare these easier, you'd turn the percentage 75% into a fraction. 75% equals 3/4. Then, you'd find a common denominator. Both 3/4 and 5/8 can be turned to have the denominator of 8. Since 5/8 already has the denominator of 8, you'd leave that alone. But, in order to get the denominator of 8 for 3/4, you'd have to multiply 4 times 2 to get 8. And, what you do to the bottom, you must do to the top, so 3 times 2 is 6. So 3/4 = 6/8.
SO, which is bigger Sally's 5/8, or John's 6/8? John ate more lunch.
