The first one includes both
Answer:
59/ 60
Step-by-step explanation:
1.9 can be expressed as 19/10
Thus, our equation becomes
19/10 -11/12.
This becomes (228 -110) / 120
= 118 / 120
Simplify by 2 to get
59/60
Answer:
12 and 28
Step-by-step explanation:
Represent the numbers using x and y. Then y - x = 16. (y is the larger one.)
Then 3y = 7x, and y = (7/3)x.
Substituting (7/3)x for y in y - x = 16, we get:
(7/3)x - x = 16.
Eliminate the fraction by multiplying all three terms by 3:
7x - 3x = 48, or 4x = 48, yielding x = 12. Then y = (7/3)(12) = 28.
