1.) c. 1,232
There are 16 ounces in 1 pint. So to solve how many ounces are in 77 pints, you should multiply 16 ounces by 77 pints.
2.) d. 10
There are 8 ounces in 1 cup. Since you have 80 ounces, you should divide that by 8 ounces (aka 1 cup).
3.) b. 2
There are 16 ounces in 1 pound. Since you have 32 ounces you should divide it by 16.
In the future, you would need to find out the conversion of measurements and then multiply/divide to solve. Make sure you keep track of your units when solving! Good luck!
