You have to make the denominators (bottom numbers) the same via multiplication, it's best to do it to the first number they meet at. that would be fifteen (15)
5×3=15
3×5=15
you then have to multiply the numerators by the respective numbers.
2×3=6
1×5=5
you then subtract the numerators normally
6-5=1
slap back on the denominator
1/15
there's your answer.
(the number you multiply them by isn't the other denominator, it just happens to be the denominators for this equation)
Quadrant I
405=360+45 405-360=45
405 is one complete counterclockwise rotation plus one half of an angle measuring 90 degrees counterclockwise rotation (=45)
The first lot is (250 x 300) x 5 = 375,000
The second lot is (350 x 400) x 5 = 700,000
375,000 + 700,000 = $1,075,000
To find the volume of the tube you will use the formula for finding the volume of a cylinder.
V = pi x r^2 x h
3.14 x 0.5^2 x 21
V = 16.485 cubic inches
The approximate volume of the tube is 16.49 cubic inches.
Write an equation and solve it. Call the length of the shorter piece "x", in this case, the longer piece is "3x". The sum of the two is equal to 116 inches.
