Answer:
2 1/10
Step-by-step explanation:
2 9/10 - 4/5. You need the minus because it says lost. That means you have to take away which is the same as minus.
The 4/5 have the same denominator as 2 9/10. This reason is because the denominator of 5 is lesser than the denomintor of 10. You don't have to do this step, but it will make it easier to solve.
2 9/10 - 8/10 = 21/10 OR 2.1 OR 2 1/10. Subtract them both to get the answer.
