Answer:
Let the 2nd fraction be a/b then according to question,
1st fraction is 4a/3b
Now,
4a/3b-a/b=2/9
(4a-3a)/3b=2/9
a/3b=2/9
compairing corresponding elements of fraction,
a=2
And,
3b=9
b=3
Answer:
1440 per hour
Step-by-step explanation:
Step-by-step explanation:
step 1. an example of difference of squares (dos) is (x + y)(x - y) = x^2 - y^2.
step 2. dos must have only 2 square rootable terms and a "-" between them.
step 3. 196x^2 - 121y^2 = (14x + 11y)(14x - 11y) works!
step 4. 5x^2 - 245 = 5(x^2 - 49) = 5(x + 7)(x - 7) works!
step 5. 27w^5 - 75w = 3w(9w^4 - 25) = 3w(3w^2 + 5)(3w^2 - 5) works!
step 6. x^4 - 100y^2 = (x^2 - 10y)(x^2 + 10y) works!
Two numbers are relatively prime if they have no factors in common. In other words, if their greatest common divisor is 1.
7 and 42- both divisible by 7
66 and 77- both divisible by 11
90 and 891- both divisible by 9
Answer would be 16 and 39
