Answer:
210 staples in each strip.
Step-by-step explanation:
4 digit palindromes must be of form abba, so being required that you use both numbers, you only have two: 1221 and 2112
First, we have to get the fractions to common denominators.
4/5 = 16/20
1/4 = 5/20
5 5/20 - 3 16/20 = 1 9/20
She put 1 9/20 extra cups in.
1/52, as there is only 1 ace of hearts in a standard deck (no jokers) of 52 cards.
