The answer is 8/9n - 1 1/3.

Explanation:

When multiplying a fraction by a whole number, you multiply the numerator by the whole number. In this case, doing so would result in 8/9n. Because the same principle would apply for the other part of the equation, we can do 4/9 x -3 to get -12/9. -12/9 is improper, so we could standardize it to get the equation’s expression in simplified form. -12/9 simplified is -1 1/3. The answer would be 8/9n - 1 1/3 because when there is a negative factor, the expression becomes a subtraction problem. Thus, your equation is 8/9n - 1 1/3.

Kim, Laura and Molly share £385
trapecia [35]
Set x equal to the amount of money Kim gets, and y for Molly's money.

 x = 2/5y, since the ratio is 2:5.
y = 105 + x, since Molly has 105 more pounds than Kim.

Substitute x into this equation, so that y = 105 + 2/5y. Subtract 2/5y from both sides to get 3/5y = 105. Divide each side by 0.6 (equivalent to 3/5) and you get y = 175, which is how much Molly has. Kim gets 2/5 of Molly's share (or 105 fewer pounds), so she has 70.

70 + 175 (Kim and Molly's shares) is equal to 245. Therefore, Laura receives the remaining 140 pounds.

140/385 = a/100
Cross multiply so that 385a is 14000. Divide by 385 to get 36.4 (rounded).

Thus, Laura receives about 36.4% of the total money. Hope this helps (:
