What is 20 divided by 4

The final result is 5, which means that 20 divided by 4 is equal to 5.

What is 20 divided by 4

When we divide 20 by 4, we are essentially finding out how many times 4 can be subtracted from 20.

To calculate this, we start by dividing the first digit of 20, which is 2, by 4. Since 2 is smaller than 4, we move to the next digit, which is 20. 20 divided by 4 is 5.

Therefore, we know that 4 can be subtracted from 20 five times.

So, we can subtract 4 multiplied by 5 (which is 20) from 20. This leaves us with 0.

Therefore, the final result is 5, which means that 20 divided by 4 is equal to 5.

10/2= a/a-9
Note: I need this NOW!!!

Answers

for this question you can say:
10/2 = a/a-9 is equal to 2a = 10a - 90
so now you should add -10a on both sides:
2a -10a = -90 ⇒ -8a = -90 ⇒ a = -90/-8 ⇒ a = 11.25 :)))
i hope this is helpful
have a nice day

10/2= a/a-9

10/2=a/a+-9

Multiply all terms by a and cancel

10a/2 = a+-9a

Simplify both sides of the equation

5a= -8a

Add 8a to both sides

5a+8a= -8a+8a

13a=0

Divide both sides by 13

13a/13=0/13

a= 0

Answer : No solution

Is 5
/12 bigger than 3/7

Answers

You can figure out if two fractions are bigger by just cross multiplying the numerator and denominator of each fraction.

$(5)/(12) (3)/(7)$

Multiply the 5 and 7, and then the 3 and 12. Be sure to start with the numerator of the first fraction.
$(5)/(12) (3)/(7)$
5 * 7 = 35, 3 * 12 = 36
So $(3)/(7)$ is bigger.

5/12 is not bigger than 3/7
