Answer:

8

That translates into (4/5)(1/4)(40).

Simplifying, from right to left:  (4/5)(10) => 8

There are three steps to this problem.

1. First, you'll need to find out what 1/4 of 40 is. An easy way to determine this is by simply dividing 40 by 1/4. (This will only work if you have to divide a fraction with a numerator of 1 by a whole number, though.) You'll end up with 10.

2. Then, you will have to determine what 4/5 of 10 is. You can't divide a number by a fraction, so you will have to multiply 10 by 4/5 instead. The picture shown is how you'll set it up.

3. Now you'll need to simply 40/5, to do this, you can simply divide 40 by 5.


Your answer will end up being 8.

Ostrovityanka [42]
(n-21)/2=4n is the equation

First, divide what is in the parentheses by 2
0.5n-10.5=4n

Then, multiply the whole equation by 2 so we have all whole numbers
n-21=8n

Move N so that it is with 8n
7n=-21

Divide 21 by 7
n=-3

Solution: The number (n) is equal to -3
