Answer 2

Given:-

• Check ,if the following ratio is are equivalent.a- 12:30 and 16:40.

Solution:-

Change the ratios to fractions:-

• 12:30=12/30
• 16:40=16/40

Now make the second fraction to simplest form and observe wheather it's equal to first fraction or not.

• 16/40
• =>8/20
• =>4/10
• =>2/5

its not equal to the first fraction but the solution has yet not finished!

Now make 12/30 to simplest form and observe it's equal to 2/5 or not.

• =>12/30
• =>6/15
• =>2/5

hence 16/40=2/5

and 12/30=2/5

hence both ratios are equivalent!

Hope it helped!
