I know part a is right, but i don’t know part b. can anyone help, please??

ruth is 6 years old

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.

i believe it’s 165 because if u add 137 and 58 u get 195 and then subtract that from 360 and there’s ur answer

answer is  

a.

7 in. x 11 in.

hope you get this right.

the scale is 1/9 my friend can't simplify 1 anymore so it will be (for every 1 there's 9)
