How to simplify 20/10

Andreyy89

In order to get the answer to this question you will have to find the common factor and then divide the numerator and denominator by the common factor to get the answer.

$\frac{20}{10}$

$CF=10$

$20\div10=2$

$10\div10=1$

$\frac{2}{1} =2$

$= \frac{2}{1} or2$

Therefore the answer is "2."

Hope this helps.

Suppose the average of 15 consectutive numbers is 15. What is the average of the first five numbers of the set?

Marina86 [1]

15x15= 225

15x + 105= 225

15x= 225-105

15x= 120

X=8

X+ (x+1) + (x+2) + (x+3)…etc all the way up too +(x+14)=225

The first five numbers of the set: 8, 9, 10, 11, 12
