Question

divide 1800 among A,B,C in the ratio 3:4:5
​

Answer 1

Answer:

total ratio = 3 + 4 + 5 = 12

A's ratio = 3/12

= 3/12 × 1800

= 3 × 150

= 450

B's ratio = 4/12

= 4/12 × 1800

= 4 × 150

= 600

C's ratio = 5/12

= 5/12 × 1800

= 5 × 150

= 750

A B C

450, 600, 750

hope you get your answer

Answer 2

Answer:

Step-by-step explanation:

Let the common number be X

then  A= 3X   B= 4X     C=5X

A + B + C = 1800

3X +4X +5X = 1800     ⇒  12X = 1800

X = $\frac{1800}{12}$     X= 150

A= 3(150) = 450

B = 4(150) =600

C= 5(150) = 750
