Answer 2

Answer:

1.C

2.3:12 or 1:4

Step-by-step explanation:

1

A:B:C=2:3:4

2+3+4=9

Based on the given choices, if we divide 9 to every choice, the answer will be:

(A) 8.3333333333

(B) 13.8888888889

(C) 35

(D) 38.8888888889

So, the only choice that has no remainder is letter C, so let's try.

To get the values of A,B, and C we have to multiply 35 to their ratios.

A=35×2

=70

B=35×3

=105

C=35×4.

=140

It was said that C(Caleb) and B'(Bobby) money was 175 more than A(Alan's), so let's see if this is true..

(B+C)-A=(105+140)-70

=245-70

=175

Therefore, the answer (C)315 is correct, besides,

A+B+C=70+105+140

=315

2.

Just add:P

2:1+4:11=3:12

if we simplify that, we'll have 1:4
