Yes, if you know that every 1 quart is equal to 4 cups then the ratio is 1:4. To find out how many cups are in 9 quarts, multiply both sides of the ration by 9. The answer would be 9:36, so there are 36 cups in 9 quarts.
Answer:
the second and third equations are true
Step-by-step explanation:
first equation
39-3*6=6*10/4+4
39-18=60/4+4
21=15+4
21=19
the equation is false
second equation
24/2^2=50-6^2-8
24/4=50-36-8
6=14-8
6=6
the equation is true
third equation
56/8+3^2=2*2^3
7+9=2*8
16=16
the equation is true
fourth equation
8^2-5^2=4^2-7
64-25=16-7
39=9
the equation is not true
