Объяснение:

2а/3 + а/6 = (4а+а)/6 = 5а/6

3х/8 - х/6 = (9х-4х)/24 = 5х/24

х/3 - у/5 = (5х-3у)/15

Verified answer

Объяснение:

2а/3 + а/6 = (2а*2)/(3*2) + а/6 = 4а/6 + а/6 =

(4а + а)/6 = 5а/6

3х/8 - х/6 = (3х * 3)/(8 * 3) - (х * 4)/(6 * 4) =

9х/24 - 4х/24 = (9х - 4х)/24 = 5х/24

х/3 - у/5 = (х * 5)/(3 * 5) - (у * 3)/(5 * 3) =

5х/15 - 3у/15 = (5х - 3у)/15
