Answer:
The amount of money that Jeff has left is $19.47
Step-by-step explanation: the math problem would be set up like this: 20/1-1/8-2/5
Step 1. Find the least common multiple of 1,8, and 5
And the Least Common multiple(LCM) of 1,8, and 5 is 40.
Step 2. Adjust fractions based on the LCM
20/1*40- 1/8*40- 2/5*40= 800/40- 5/40- 16/40
Step 3. subtract the numerators over the denominator
800-5-16/40 = 779/40
So, your answer to this question is 779/40. Hope this helps!!!
