Answer:
1 5/8 . or 39/24
Explanation:
Start with the numbers in the brackets
2/3 + 5/8
Use the LCM, which is 24
Multiply the numerators by the numbers which are used to multiply the denominators to 24
16/24 + 15/24 = 31/24
Now return to the 1/3 outside the bracket
1/3 + 31/24
Multiply the numerator and denominator by 8
8/24 + 31/24 = 39/24
Either keep it as 39/24 or the mixed fraction 1 15/24 to 1 5/8
