Question

Matt had a full jar of marbles. He gave Kayla 3/4 of the marbles. Then Kayla returned 1/3 of a jar's worth of marbles to the jar. how much of the jar is full of marbles?

Answer 1

Answer: 7/12 jar is full of marbles

Explanation:

Matt had full Jar of Marbles = 1

After giving 3/4 to Kayla , jar has marbles =
`1-(3)/(4)  \\=(4)/(4) -(3)/(4) \\=(1)/(4)`

Kayla returned = 1/3 of Jar

Now jar has marbles = 1/3+ 1/4

= 4/12 + 3/12 [ making denominator same]

= 7/12
