In general the binomial expansion is

So in our case, because we want ascending powers of x we'll write,

We need to calculate the binomial coefficients:






Multiplying ratios is just like multiplying fractions.
Ex:
5:10 = 5/10
5:10 · 2:20 = 5/10·2/20.
keep 5/10,
simplify 2/20 to 1/10,
multiply 5·1, and 10·10, and the answer is 5/100 or .05
Answer:
20 books
Step-by-step explanation:
given that the shelf can hold 25 1/2 lbs (i.e 25.5 lbs), and that each book weighs 1 1/4 ln (i.e 1.25 lbs)
number of books which the shelf can hold
= weight that the shelf can hold ÷ weight of each book
= 25.5 ÷ 1.25
= 20.4 books
because having 0.4 of a book (i.e part of a book) would not be very feasable, we have to round the number of books down to the nearest whole number)
20.4 books rounded down to nearest whole number = 20 books (answer)
