When Arjun makes hot cocoa, he adds 20ml of chocolate syrup for every 3 ounces of hot water. Arjun's brother, Eli, adds 45mL of chocolate syrup for every 6 ounces of hot water.

For every one ounce of hot water, Arjun adds 6.67 mK of chocolate syrup and for every 1 ounce of hot water, Eli adds 7.5 mL of chocolate syrup. i wasn’t sure the question in this

Arjun's hot cocoa

the ratio = 20 : 3

or you can write as fraction 20/3

Eli's hot cocoa

the ratio = 45 : 6

or you can write as fraction 45/6

Compare

20/3 ... 45/6

40/6 ... 45/6

40/6 < 45/6

The one more chocolatey is Eli's hot cocoa, because the fraction is bigger
