1.Simplify 25/27÷(3/7+4/9)×3¹/7
2.Simplify9/11of3/5of(17/15÷13/25 )÷2³/13

Number 1 = 25/27 / (3/7+4:9)x3 1/7

= 25/27 / (3/7+4/9) x 31/7

= 25/27 /(55/63) x 31/7

= 25/27 x 63/55 x 31/7

= 155/33

Number 2 sorry  for the scend one i dont realy have time to awnser this one # apeex people

Step-by-step explanation:

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
