My 6 friends is going to be at my sleepover I will need good amount of milkshakes 1. I would need 7 gallons of milk 2. I would need (4/5) of ice cream Now I multiply all together to see if it’s enough for my guest 6 times (4/5) 5 3/5 I’ll think this would be a perfect amount.

Is this right?

No, your calculation is incorrect. To determine the amount of milkshake you need, you should multiply the number of friends (6) by the amount of ice cream needed (4/5) and then multiply that result by the number of gallons of milk needed (7).

So, the correct calculation would be:

6 friends x (4/5) x 7 gallons = 26.4 gallons

Therefore, you would need approximately 26.4 gallons of milkshake for your sleepover with 6 friends.
