Question

if 30% of a equal to 50% of b then find b:a​

Answer 1

Answer:

5:3

Step-by-step explanation:

30% of a=50% of b

=>30a/100=50b/100

=>3a/10=b/2

=>3a*2=10*b

=>6a=10b

=>a/b=10/6

=>a/b=5/3

Therefore: a:b=5:3

Answer 2

As per the data given in the question,

We have to determine the value of ratio between a and b.

As per question,

It is given that,

30% of a equal to 50% of b

So, writing the above expression mathematically,

We will get,

$30\%\: of\:a= 50\%\: of\: b\\=>\frac{30}{100}\times a = \frac{50}{100}\times b\\=>30a=50b\\=>\frac{a}{b} = \frac{50}{30}\\=>\frac{a}{b} = \frac{5}{3}$

Hence, ratio between a and b will be 5:3.
