Sagot :
Answer:
57 and 76
Step-by-step explanation:
the ratio = 3 : 4
=> the sum : 3+4=7 ( equivalent with 133)
so the numbers are :
3/7 × 133 = 57 and
4/7 × 133 = 76.
Answer:
The numbers are x = 57 and y = 76.
Step-by-step explanation:
Represent the numbers by x and y.
x 3
Then --- = -----
y 4
Also, x + y = 133. We can solve this for either x or y and substitute the result into the above equation. Solving for y, we get 133 - x = y, and so the above equation becomes
x 3
--------- = ------
133 - x 4
Cross multiplying yields
4x = 399 - 3x, or 7x = 399, or x = 57. Then, since y = 133 - x, y = 76.
The numbers are x = 57 and y = 76.
