Question

Are the ratios 30:12 and 40:16 equal if reduced?

Answer 1

Answer:

yes both given ratios are equal if reduced.  

Step-by-step explanation:

On simplifying 30:12  we can see that common divisor of 30 and 12 is 6

therefore on dividing it by 6 ,we get ratio 5:2

Likewise 40 :16 has common divisor as 8 , therefore on dividing the ratio by 8 ,we get ratio as 5:2 again

Here we can see that simplest form of ratios for both is same as 5:2  

therefore the answer is yes both given ratios are equal if reduced.  

Answer 2

Yes, borh ratios when reduced are 5:2. 30:12 is 5:2 because both are divisible by 6. 30/6=5 and 12/6=2. 40:16 is 5:2 because both are divisible by 8, 40/8=5 and 16/8=2
