20% off the original makes it 80%. Then, 25% off of 80% makes it 60%. The final price reduction is 40%

Convert percentages to units.
100% - 20% = 80% = 0.8
100% - 25% = 75% = 0.75

Then multiply those together:
0.8*0.75=0.6=60%

100% - 60% = 40%. That's the overall price percentage reduction.

P.S. You can convert percentages to units by diving % by 100 for example 100% divided by 100 is equal to 1.
And vice versa aka multiply units by 100 and you get %, for example 0.8 times 100 is 80%

In 36 days will the science and math teachers both give tests on the same day again.

<u>Step-by-step explanation:</u>

Here we have , The 6th grade science teacher gives a test every 12 days and the math teacher gives a test every 9 days. Today, both the science and math are giving tests. We need to find In how many days will the science and math teachers both give tests on the same day again . Let's find out:

It's given that science teacher gives a test every 12 days and the math teacher gives a test every 9 days . In order to find the number of days after which they'll give test at same day , we will find LCM of 12 & 9 . i.e.

⇒ $12(1)=12\\12(2)=24\\12(3)=36$ and ,
