Question

If 3/8 a= 80% of b =0.5 of c then a:b:c ?

Answer 1

Answer:

32:15:30

Step-by-step explanation:

3/8 a= 4/5 b

a/b=8×4/5×3=32/15

And

b=1/2 of c

b/c=1/2

On comparing both value of b we have to make it same

So multiply b/c=1×15/2×15=15/30

So a:b:c=32:15:30

Answer 2

$\mathfrak{\underline{\underline{\green{Answer:-}}}}$

a : b : c = 32 : 15 : 24

$\mathfrak{\underline{\underline{\green{Explanation:-}}}}$

Given:

$\mathsf{\dfrac{3}{8} a}$ = 80% of b = 0.5 of c

To Find:

a:b:c

Solution:

Given that,

$\mathsf{\dfrac{3}{8} a}$ = 80% of b = 0.5 of c

Therefore

$\mathsf{\dfrac{3a}{8} = \dfrac{80b}{100} = \dfrac{5c}{10}}$

$\mathsf{\dfrac{3a}{8} = \dfrac{4b}{5} = \dfrac{c}{2}}$

By dividing with 3

$\mathsf{\dfrac{3a}{8 \times 3} = \dfrac{4b}{5 \times 3} = \dfrac{c}{2 \times 3}}$

$\mathsf{\dfrac{a}{8} = \dfrac{4b}{15} = \dfrac{c}{6}}$

Now, By diving with 4

$\mathsf{\dfrac{a}{8 × 4} = \dfrac{4b}{15 × 4} = \dfrac{c}{6 × 4}}$

$\mathsf{\dfrac{a}{32} = \dfrac{b}{15} = \dfrac{c}{24}}$

HENCE

a : b : c = 32 : 15 : 24
