Question

a:b= 7½ : 5 and b:c = 1 ¼ : 3 . FIND a:b:c please urgent
​

Answer 1

Answer:

Step-by-step explanation:

We know that 7(1/2) and 1(1/4) are mixed fractions so

7(1/2)= 15/2 and 1(1/4) = 5/4

a:b = a/b

So

a/b= (15/2)(5/1)

a/b= 3/2

b/c= (5/4)(3/1)

b/c= 5/12

a= 15/2

b= 5

c= 12

Therefore

a/b/c = (15/2)/(5/1)/(12/1)

a/b/c= (15/2)(1/5)(1/12)

a/b/c= (1/8)
