I know that you need to use subtracting.
you also need the make the denominators the same.
Find what the LCM for both numbers 5 and 10.
5: 5, 10, 15
10: 10,20,30
Both have 10 and common.
Do 4/5 x 2/2 and you get 8/10.
Then do 2 1/10 x 1/1 and you get 2 1/10.
then subtract 8/10 by 2 1/10.
You will get 2 7/10 as your answer.
Factors are the building blocks of multiplication. They are the numbers that you can multiply together to produce another number: 2 and 10 are factors of 20, as are 4 and 5 and 1 and 20. To factor a number is to rewrite it as a product. 20 = 4 • 5.
Likewise to factor a polynomial, you rewrite it as a product. Just as any integer can be written as the product of factors, so too can any monomial or polynomial be expressed as a product of factors. Factoring is very helpful in simplifying and solving equations using polynomials.
A prime factor is similar to a prime number—it has only itself and 1 as factors. The process of breaking a number down into its prime factors is called prime factorization.
