Question

Jason and Monica each need to put $1$ gallon of water into a pot. Jason has a measuring cup that hold $1$ cup. Monica has a measuring cup that holds $1$ pint. How many more cup does Jason need to fill the measuring cup than Monica?

Answer 1

Find the difference in the numbers of cup of Jason and Monica each need to put $1$ gallon of water into a pot.

• Jason has the measuring cup holding $1$cup or $8$ fluid ounce. $\left(\because 1\text{cup}=8\text{fluid ounce}\right)$
• Monica has a measuring cup holding $1$ pint or $16$ fluid ounce. $\left(\because 1\text{pint}=16\text{fluid ounce}\right)$

$\because$Each need to fill $1$ gallon of water that is equal to $128$ fluid ounce.

$\therefore$Jason need to fill $\frac{128}{8}=16$ measuring cup.

• Monica needs to fill $\frac{128}{16}=8$ measuring cup.

The difference in numbers of cups of Jason and Monica is $16-8=8$ measuring cup.

Hence, Jason needs to fill $8$ more measuring cup than Monica.
