7 x 37 mentally using the Distributive Property.

the answer would be 259

Step-by-step explanation:

and you can't solve this using distributive property sorry  

but I hope this helps you

cause based on the way the problem is written it really seems you meant multiplication

Well you would convert the fractions to fractions with the same denominator which would make it 14/21 for the first friend and 15/21 for the second friend. But the question is asking how much is left so you have to subtract what is left in each bottle. The first friend has 7/21 left and the second friend has 6/21 left. So, the answer is 1/21.
