How many pairs of positive integers (a, b) satisfy 1/a} + 1/b}=2/7?

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.

hope that , fam!

-une, your fren : )

i believe it is the square root of 122 because when you turn it on it's side, to where the 5 inches is on the bottom, it looks like it is the same length.

10 times 13 = 130

10 times 13 = 130

130 + 130 = 260

if this you out can you make this answer the brainliest?
