Answer:
15:21:35
Step-by-step explanation:
to find this answer you must find a ratio in which both bs are the same
so
multiple a:b by 3 and b:c by 7
15:21 21:35
then you can put the bs together
15:21:35
that is your answer
Answer:
15 : 21 : 35
Step-by-step explanation:
Now, we see that both ratios contain B.
We need to find a common value for B so all values can be linked.
Multiply Ratio 1 by 3 and Ratio 2 by 7 :
⇒ A : B = 3 × 5 : 3 × 7 = 15 : 21
⇒ B : C = 7 × 3 : 7 × 5 = 21 : 35
Now we see B has the same value in both ratios.
Hence, the ratio we need to find is :
A : B : C = 15 : 21 : 35
