ایک آرٹ ٹیچر 20 اونس پیلے رنگ کے پینٹ کو 8 اونس سرخ پینٹ کے ساتھ ملاتا ہے۔ اسی تناسب کو برقرار رکھنے کے لیے اسے کتنے اونس پیلے رنگ کے پینٹ کے 18 اونس سرخ پینٹ کے ساتھ ملانے کی ضرورت ہوگی؟
Explanation

Step 1 - The unitary method can be used in order to determine the total amount of yellow paint she needs to mix with 18 ounces of red paint to maintain the same proportion.

Step 2 - Let the total amount of yellow paint she needs be 'x'.

Step 3 - So, the value of 'x' can be calculated as:

x = 18/8 x 20

Step 4 - Simplify the above expression.

x = 45 ounces.
