Flaming BBQ Restaurant makes a dipping sauce with 9 ml of hot sauce for every 6 ounces of barbecue sauce

the correct question in the attached figure

we know that

[ratio dipping sauce]=[9 ml hot sauce]/[6 ounces barbecue sauce]
[ratio dipping sauce]=[9/6]------------> 3/2----> 1.5
that means
1.5/1-----> for each 1.5 ml hot sauce-------> has 1 ounce of barbecue sauce

therefore

the answer is
Any mixture that has the ratio 1.5 to 1 will taste the same as flaming BBQ's dipping sauce
