Answer:
153/20
Step-by-step explanation:
We want to have the mixed fraction turned into a improper fraction to make adding them both easier. We would change 5 2/8 to 42/8 and 2 4/10 to 24/10.
We now need to get them a common denominator. The LCM (least common multiple) of 8 and 10 is 40, so we multiply 42/8 by 5/5 getting us 210/40 and 24/10 by 4/4 to get 96/40.
Finally, we add them then simplify. 96/40 + 210/40 is 306/40. We then simplify that to 153/20.
Answer:
Its incorrect
Step-by-step explanation:
Area is width times height but in this case its 3 numbers so after you did width time height if I'm not mistaken you multiply that number by 4 so you were supposed to multiply 5 and 6 the answer is 30 and then multiply 30 by 4 which is 120 I think.
Answer:
39.30
Step-by-step explanation:
When you divide you usually don't get a full number, so, when you get a answer that has a long decimal number, you round the two numbers after the decimal point, so, 39.29 would be 39.30. I'm pretty sure that is your answer. If it is wrong I sincerely apologize.
