Answer:
Step-by-step explanation:
If I have 90 pounds shared between A, B, and C, then in a mathematical equation,
A + B + C = 90
However, we have way too many unknowns.
We are told that the ratio of A to B is 1 to 2, or
and cross multiplying,
2A = B or
We are also told that the ratio of B to C is 4 to 3, or
and cross multiplying,
3B = 4C or
Now we have everything in terms of B, so we will rewrite it like that:
, and
and
9B = 360 so
B = 40. If B is 40 and A is half of B, then A is 20.
