An 8-ounce can of tomatoes costs $1.14. A 12-ounce can cost $1.75. Which can of tomatoes costs the least per ounce? pls help i will have more questions

Sorry guys but as you have a small brain

Tomas is making trail mix using granola and walnuts. he can spend a total of $12 on the ingredients. he buys 3 pounds of granola that costs $2.00 per pound. the walnuts cost $6 per pound. he uses the equation to represent the total cost, where x represents the number of pounds of granola and y represents the number of pounds of walnuts. he solves the equation for y, the number of pounds of walnuts he can buy. answer- b tomas added 6 to both sides of the equation instead of subtracting 6. just took the test

How do i take any fraction and make it into a decimal or percentage?
