When you need a fraction of a number like 1/3 of 9 how do you find out how much you need?
1 answer:
To find out how much you need when you need a fraction of a number like 1/3 of 9, you can multiply the whole number by the fraction in most cases.
In some cases however, you can convert the whole number into a fraction and then divide it to get the amount in fractional units that you require.
For example:
1/3 of 9
Convert 9 to a fraction.
1/3 / 9/1
1/3 x 9/1 = 3/9
Therefore you would need 3 of 9 for 1/3.

6x + (-9) or 6x - 9
Try looking at the terms for the same things. Such as the variable like X and the negatives add together and make a negative
It would take 5 hours because you take 3 and divide that by 1.5 & you get 2 so 5 multiplied by 2 is 10. it would take her 30 minutes per page
Have you tried using a calculator
Set both fraction to a common denominator
7/16 and 4/16
now add them together
7/16 + 4/16 = 11/16
now subtract that from a full cake
16/16 - 11/16 = 5/16
there are 5/16 of the cake left
I think x = 1/176
1/2x + 10 = - 1/4x + 54
1/2x + 10 = - 1/4x + 54, x 0
1/2x - 1/4x = 54 - 10
2-1 over 4x = 44
1/4x = 44
1 = 176x
x = 1/176
I could be wrong.
