Why does 25/10 equal 2 1/2

Mathematics

Answer:

25/10 is equal to (20+5)/10, which is also equal to 20/10 + 5/10. 20/10 = 2, and 5/10 = 1/2, so by simplifying, 20/10 + 5/10 = 2 + 1/2 = 2 1/2

25/10 equal 2 1/2 because when you simplify the 25/10 to the least, it will be 5/2. 2 fits twice into 5 and there is a remainder of 1/2. So, it's 2 1/2.

Answer:

She has 52 cards per deck, and b decks.

This means she has 52b cards.

For 1 deck, she has 52 cards, or 52×1 cards.

For 2 decks, she has 104 cards, or 52×1 cards.

For 5 decks, she has 260 cards, or 52×5 cards.

Therefore, for b decks, she has 52×b, or 52b cards.
