Describe an error in the work shown below. Find an expression equivalent to 18 +30.
Factors of 18: 1, 2, 3, 6, 9, 18
Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30

18+30=6(3+10)

6 times 10 is not 30 it is 60 the and should be 18+30=3(6+10)

Step-by-step explanation:

The factor that multiplies with 6 to get 18 is 3 but the factor that multiplies with 6 to get 30 is 5.

The numbers in parenthesis should be a 5 and not a 10.

18 + 30 = 6(3 + 5)
