Answer: 2.4x+2.8=10
Explanation:
First, you have to convert your fraction into a decimal to make it easier in your equation later on. 2 2/5= 12/5= 2.4
Next, you should subtract the amount you have set aside from the total amount. 10- 2.8= 7.2
Finally, you should use the decimal you converted from your fraction and either divide it by the amount you have after you have set aside the portion need for the sauce. 7.3/2.4=2
