Answer:
5. 12
6. 12
7. 20
Step-by-step explanation:
5. if it's the friend does 3 cars for every 2 cars you do, then its multiplying itself. so 4 for you would be 6 for the friend, as for 6 to 9, and 8 to 12.
6. just like in 5 it's 5 shirts for every 2 sweaters. so 10 shirts would be 4 sweaters, 15 would be 6, 20 would be 8, 25 would be 10, and 30 would be 12.
7. this ratio is 5 olives for every 3 croutons. since u have 12 croutons, that's 3 times 4 so you do the same thing to the olives. 5 times 4 which equals 20 olives for 12 croutons.
