A = lw

Plug in what we know:

25/54 = (5/9)w

Divide 5/9 to both sides or multiply by its reciprocal, 9/5:

25/54 * 9/5 = w

Multiply the numerators and denominators together:

225/270 = w

Simplify:

Nathan has a collection of 220 baseball cards. He lets his brother 1/4 of his collection and sells 20% of his collection to the
tatyana61 [14]

<u>Answer:</u>

The baseball cards remain in Nathan’s collection is 106 cards

<u>Explanation:</u>

Total number of cards Nathan has= 220

Number of cards he let his brother have = 1/4 of his collection

=\frac{1}{4} \times 220 = 55 cards

Number of cards he sells = 20% of his collection

=\frac{20}{100} \times 220

=44 cards

No of cards he gives to his friends=15 cards

Remaining cards = total number of cards – (no of cards he gave to his brother+ cards he sold+ cards he gave to this friends)

= 220 – ( 55+44+15)

=220-114

=106 cards

baseball cards remain in Nathan’s collection is 106 cards
