#525# #"mL"# coffee

(I take it that the "coffee" and the "milk coffee" are two different things.) #"milk"/"milk coffee" = 2/5# Let #x# be the volume of the milk coffee. #2/5=(150"mL")/x# #2x=5*150# #2x=750# #x=750/2# #x=375# So, there is #375# #"mL"# of milk coffee in the cup. Add this to the milk's volume: #375# #"mL"# milk coffee + #150# #"mL"# milk #= 525# #"mL"# coffee

undefined To find the volume of the coffee in a cup of cappuccino, if 150 mL of milk is used, you can use the given ratio of milk to milk coffee, which is 2:5. First, determine the total parts in the ratio by adding 2 (for milk) and 5 (for milk coffee), which equals 7 parts. Then, divide the volume of milk (150 mL) by the total parts (7) and multiply the result by the parts representing milk coffee (5).

Calculation:
Volume of milk coffee = (Volume of milk / Total parts) * Parts representing milk coffee
Volume of milk coffee = (150 mL / 7) * 5
Volume of milk coffee ≈ 107.14 mL

Therefore, the volume of coffee in a cup of cappuccino is approximately 107.14 mL when 150 mL of milk is used.
