Steps:
1. since the least common multiple of 8 and 4 is 8, you would have to make both of the denominators 8.
2. 2 times 4 equals 8, 2 times 3 equals 6
3. 35 3/4 now becomes 35 6/8
4. your new problem is 35 6/8 - 1/8
5. 6 -1= 5
6. your answer is 35 5/8
5^3=125; 2.5^2=6.25. So the answer to your first question is 125, and the second one is 6.25
Well here's your answer straight <u><em>he must pay 29.82$ </em></u>and here's my work,
- 20% of 35 is 7 and since its 20% off we must subtract 35-7=28
- Next it said there's a 6.5 tax so that means we are adding on to 28$
- 6.5 of 28 is 1.82 so we add 28+1.82 which equals your answer 29.82
