Will odd numbers when added always make even numbers

Mathematics
1 answer:
Fittoniya [83]3 years ago

Always. consider 2x which is always even (divisible by 2)

then 2x+1 is the form of all odd numbers.

add 2 of the odd numbers together to get (2x+1)(2y+1) = (4y² +2x +2y) + 1

the part in parentheses is always even can you see why? then adding one again always gives us an odd number.

20 is what percent of 52
Maslowich
The process here is finding out the smallest number's % towards the largest number.

Divide 20 by 52:
20/52 = 0.38 (estimated) | This is the % in decimal form, which is 38%.

Conclusion: 20 is 38% of 52.

{---Further Elaboration for Future Reference---}

Finding the Smallest Number:

What number is 25% of 60?

Multiply 60 by the decimal form of 25%.
60 * 0.25 = 15 | 15 is 25% of 60.

Finding the Percentage. (Like what we already did.)

30 is what percent of 150?

Divide 30 by 150.
30/150 = 0.2 | 30 is 20% of 150.

Finding the Largest Number.

12 is 30% of what number?

Divide 12 by the decimal form of 30%.
12/0.3 = 40 | 12 is 30% of 40.

I hope this helps, have a great rest of your day! ^ ^
