On a fishing excursion, jeannie keeps 1/4 of the fish she catches and releases the remainder of the fish back into the lake. if

postnew [5]

To find 1/3 of 3/4 we divide the fraction by 3 which is equal to 1/4 or alternatively we can multiply the denominator by 3 which gives us 3/12 (1/4=3/12)
So 3/12 of the realesed fish are trout

To find 2/3 of 1/4 we need to first divide 1/4 by 3 which is equal to multiplying the denominator times 3 which gives us 1/12 and then we multiply by 2 which gives us 2/12
So 2/12 of the kept fish are trout

To find the total amount we add 2/12 and 3/12
3/12+2/12= 5/12

ANSWER:
5/12 of the fish she catches are trout

A family member has some five dollar bills and one dollar bills in their wallet. Altogether she has 18 bills and a total of $62.

Pepsi [2]

X - the number of five dollar bills
y - the number of one dollar bills

She has 18 bills in total.
$x+y=18 \\ y=18-x$

She has $62.
$5x+y=62 \\
y=62-5x$

Set both expressions equal to each other:
$18-x=62-5x \\
-x+5x=62-18 \\
4x=44 \\
x=11 \\ \\ y=18-x=18-11=7$

She has 11 five dollar bills and 7 one dollar bills.
