Answer 1

Answer:

kk this is u r answer please mark me as brainlist answer and thanks for my answer

Step-by-step explanation:

first leave p =3/7 and s = 2/15 now see q =2/21 and 1/9 and r = 2/3 and 1/5 now add this so take LCM of 21 and 9 so LCM is 63 so 2/ 21 ×3/3= 6/63 and 1/9 × 7/7=7/63 and now add and answer is 13/63 so we find q value now r so same take LCM of r is 3 and 5 is 15 and so 2/3 ×5/5=10/15 and 1/5 ×3/3= 3/15 so 10/15+ 3/15= 13/15 so answer is 3/7:13/63:13/15:2/15
