20/24-(-18/24)=38/24
Subtracting a negative is adding a positive.
20/24+18/38
38/24
24 goes into 38 once and 14/24 is left over.
1 14/24
Divide the fraction by two for simplest form.
1 7/12
Answer:
B. is your answer
Step-by-step explanation:
V=whl=7·6.5·7=318.5
Answer:
9/20
Step-by-step explanation:
first you have to make 1 1/4 an improper fraction so since the denominator is 4 you add 4 to the numerator which is 1 so your fraction would be 5/4.
Second you make the denominators the same so you have to multiply them together. but since your multiplying the denominators you have to multiply the numerator as well. so for 5/4 you would multiply both the numerator and denominator by 10 so your fraction will now be 50/40. now you multiply 8/10 by 4 so your new fraction is now 32/40
Third you subtract. you only have to subtract the numerators so 50-32 is 18 so your answer is 18/40
Last you need to simplify the highest number you can divide both of them by is 2 so now you divide 18 by 2 which makes 9 then you divide 40 by 2 which is 20 so your answer is 9/20
Sorry i'm not the best at explaining things but i tried my best
Hope this helps you out and have a great day : )
we are asked to divide 5 over 536. Since the number we are diving by is larger than 5, the answer is a decimal number, the division can be done like this:
We need to add zeroes to the 5 until we get a number that is largest than 536, every time we do that we also add a zero to the answer, like this:
Now, if we multiply 536 by 9 we get 4824, we subtract that from 5000, like this:
Therefore, the answer is 0.009 with a remainder of 176
