Deon had 3/5 of a spool of yarn. He used 3/7 of it for his project. What fraction of the spool was used for his project?

6/35

Step-by-step explanation:

TO start you have to get a common denominator.

The lowest common multiple is 35, which just requires you to multiply the bottom two numbers to their fractions.

so you would do 3/5 times 7 on the top and bottom to get 21/35

then on the other one you would take 2/7 times 5 to get 15/35

you now have 21/35-15/25 or essentially 21-15 which is 6 and keep the denominator

you come out with 6/35

7/2

(decimal: 3.5)

step-by-step explanation:

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110
