Answer:
C. =6.633
Step-by-step explanation:
9/10 - 2/5 + 1/3
= 5/6 (Decimal: 0.8333333)
Subtract:
9/10 - 2/5 = 9/10 - 2 . 2/5 . 2
= 9/10 - 4/10
= 9 - 4/10
= 5/10
= 1/2
The common denominator you can calculate as the least common multiple of the both denominators LCM ( 10, 5) = 10
Add: 1/2 + 1/3 = 1 . 3/2 . 3 + 1 . 2/3 . 2
= 3/6 + 2/6
= 3 + 2/6
= 5/6
The common denominator you can calculate as the least common multiple of the both denominators LCM ( 2, 3) = 6
Answer in Lowest term is: 5/6 or Decimal: 0.8333333
Hope that helps!!!
