Fractions can be read as division. The top number (also called the numerator) is divided by the bottom number (also called the denominator).

$\frac{4}{10}$ 4 / 10 = 0.4

Factor mn - 4m - 5n + 20

anastassius [24]

Mn - 4m - 5n + 20

In this, mn and -4m have a common factor; m. So we can take that out to make it:

m(n-4) -5n + 20

Now, -5n + 20 also has a common factor which is 5, because 20/5 gives you 4, and 5/5 equals 1. So we can talk out that -5 (it doesn't need to be negative, but negatives on variable, no gusta). So you'd get

m(n-4)-5(n-4) OR m(n-4)+5(-n+4)
