Question

Given that a:b:c=75: 120: 132,
(i) simplify a : b:c.
(ii) find b:a,
(ii) find b:c.​

Answer 1

Answer:

(i) 25:40:44

(ii) 8:5

(iii) 10:11

Step-by-step explanation:

It's given that:

a:b:c = 75: 120: 132

Now for,

(i) Let's find us the common multiplier in the three terms.

   And we find it is = 3

now, divide all of the terms by 3.

(75÷3):(120÷3):(132÷3) = 25:40:44 (ANS)

(ii) It's given that:

     b = 120

     a = 75

Now, let's find the common ones.

And we find = 3,5 or, 15

now, divide all of the terms by 15.

(120÷3):(75÷3) = 8:5 (ANS)

(iii) It's given that,

    b = 120

   c = 132

Now, let's find the common ones.

And we find = 3,4, or, 12

now, divide all of the terms by 12.

(120÷12):(132÷12) = 10:11 (ANS)

Hopefully, it will HELP you and if it Please give it a BRAINLIEST.

Thank you EVERYONE, for EVERYTHING.

Answer 2

Answer:

Let a be 75x ,b be 120x and c be 132 X

(i)a : b : c = 75 : 120 : 132 =75/120/132

Dividing by 3

we get

25:40:44

(ii) b:a = 120x/75x=8/5

(iii) b:c = 120x/132x = 10/11
