Choose the correct problem for the fraction . 1 .) 13 ÷ 12
2.) 12 ÷ 13
3.) 12 ÷ 10
4.) 12 x 13

Well obviously 4 is out but I’m not given a fraction. Just here’s a thing, the dividision is sign basically means the line that separates the numerator and the denominator in a fraction and it basically reads divided by. So if the fraction is 12/13, then it would be 12 divided by 13 which is B but thats just an example. There was no given fraction.

step-by-step explanation:

step-by-step explanation:

part a. the differences are decreasing, so we know the sequence is not arithmetic. the ratios are constant (=3/4), so we know the sequence is geometric.

part b. from part a, we know the common ratio is 3/4, so each term is 3/4 of the one before. the initial term is the number of gallons at h=1.

g[h] = (3/4)·g[h-1]

g[1] = 384 . . . . initial value required for a recursive definition

part c. the general formula for a geometric sequence is

a[n] = a[1]·r^(n-1)

we have a[1] = 384, r = 3/4, and the term number given by h. the formula that follows is

g[h] = 384·(3/4)^(h-1)

part d. filling in the value and doing the arithmetic, we have

g[12] = 384·(3/4)^11 ≈ 384·0.042235136 ≈ 16.2183 . . gallons

part e. each gallon is 4 quarts, so

16.2183 gal × 4 qt/gal = 64.8732 qt
