Solution

1. (1/3) +2/5)

take lcd of as 3*5 = 15

So, ( 1*5 +2*3)/15

= (11/15

2) Intial amt = $600

spend 1/3 on muffler = (1/3)*600 = $200

2/5th on engine repairs = (2/5)*600 = $240

Remaining = 600 -200 -240 = $160

3. let the no. multiplied with 5/12 be x

(5/12)*x = 2/7

5x/12 = 2/7

mullyiply both sides by 12/5 to isolate x:

(5x/12)(12/5) = (2/7)(12/5)

x =24/35

4) (2/7) / (5/12)

(2/7)*(12/5)

= 24/35
