Hi!

When we divide a fraction for a fraction we have to multiply the first fraction for the opposite of the second (the one we're dividing for).

Let's do an example.

16/8 : 4/6 = 16/8 * 6/4

Where necessary you can do cross-semplifying.

So, 16 and 4 can be divided both for 4.

8 and 6 both for 2.

So we have 4/4*3/1

You can also semplify numerator and denominator...

4/4 = 1

1*3 = 3

The quotient of two less than a number and five is eight
postnew [5]

Answer:

The number is 42.

Step-by-step explanation:

Let x be the unknown number.

"two less than a number" is x - 2

Quotient means the result of a division.

(x - 2)/5 = 8

Multiply both sides by 5.

x - 2 = 40

Add 2 to both sides.

x = 42

Answer: The number is 42.

Check.

Start with 42. 2 less than 42 is 40. The quotient of 40 and 5 is 40/5 which is 8. The answer is correct.
