So i’m pretty sure you’re supposed to add them. first you have to find a common denominator. the easiest way to do this is to multiply the denominators! so
3•7=21
we have our denominator
now we have to convert both fractions into new fractions with the denominator
so for the first fraction, we got 21 by multiplying by 7, so we have to multiply the whole equation by 7:
2•7/3•7
that makes 14/21 (our first fraction!)
now the second fraction we multiplied by 3, so:
5•3/7•3
that makes 15/21
now we have to add them!
14/21 + 15/21 = 29/21
there’s one complete number in that fraction, because 21/21 reduces to 1/1 which is just one. but we still have 8 left over, so the simplified answer is:
1 8/21

hope this helped!!

A pound of guinea pig pellets is about 3 cups of food.Each guinea pig eats 1/4 cup is pellets a day. How many days will the pell
kompoz [17]

Answer:

The pellet will last after 12 days

Step-by-step explanation:

* Lets change the story problem to equations to solve it

- There is a pound of guinea pig pellets

- One pound of pellets is about three cups of food

- Each guinea pig eats 1/4 cup of pellets a day

* Lets use these information to solve the problem

∵ One pound of guinea = 3 cups of food

∵ The guinea pig eats 1/4 cup a day

- The pig can finish one cup in four days

∵ The number of days = number of cups ÷ the eaten in a day

∵ The number of cup = 3 cups

∵ The eaten pellets in a day = 1/4

∴ The number of days = 3 ÷ 1/4 = 3 × 4/1 = 12 days

* The pellet will last after 12 days
