Q2
Bronze to aluminum is 25:2
The alloy is bronze plus aluminum, so by adding 25 + 2 you get 27.
Bronze to total is 25:27
25 is 27 as x is to 55
25/27 = x/55
27x = 25 * 55
x = 50.926
Answer: 50.926 kg of bronze

Step-by-step explanation:
Unit rate = $32/(5 pounds) = $6.40/pound
[You can convert that to smaller units:
$6.40/pound × (1 pound)/(16 ounces) = $0.40/ounce]
:::::
Cost = (number of pounds) × $6.40/pound
:::::
12 pounds × $6.40/pound = $76.80
