Answer:
4:3 or 1:0
Step-by-step explanation:
Meriden would need 2 1/4 cups of sugar because 3*3/4=2 1/4
Leah, she ran farther by 1/21
How you get the answer:
5/7
Multiply 7x3 to get the denominator and do the same to the numerator 5x3! Which is 15/21
To get 21 from 2/3 is to multiply 3x7 (denominator) and 2x7 (numerator) to get 14/21
15/21 > 14/21 so Leah ran farther by 1/21
