Answer:

12 3/8

Step-by-step explanation:

8-1/2+5-1/8

8+5  -1/2 - 1/8

Lets get a common denominator of 8

8+5 - 1/2 *4/4 - 1/8

8+5 - 4/8 - 1/8

Combine the whole numbers and the fractions

13 -5/8

Now we need to borrow from the whole number

12 + 1 - 5/8

12 + 8/8 -5/8

12 +3/8

12 3/8

Answer:

do 3/22 × 1/6 which is also reduced to --> 1/22 × 1/2 and that is 1/44 but you should be able to jist plug 3/22÷ 6 in if you take middle/highschool math anyways

7x = 210
x=30
Amount the sister earns = 30
Amount I earn = 2(30) = 60
