She gave 1/3 of cookies for her husband 1/4 of the cookies to her son and 1/6 of a cookies to her neighbor she ate the remaining

beks73 [17]

She made 15 cookies

Solution:

Let "x" be the number of cookies she made

She gave 1/3 of cookies for her husband

Therefore,

$Husband = \frac{1}{3}x$

Find the remaining

$Remaining = x - \frac{x}{3} = \frac{3x-x}{3} = \frac{2x}{3}$

1/4 of the cookies to her son

Therefore,

$son = \frac{1}{4} \times \frac{2x}{3} = \frac{x}{6}$

Now again find the remaining

$Remaining = \frac{2x}{3} - \frac{x}{6} = \frac{x}{2}$

1/6 of a cookies to her neighbor

$Neighbor = \frac{1}{6} \times \frac{x}{2} = \frac{x}{12}$

Now again find the remaining

$Remaining = \frac{x}{2} - \frac{x}{12} = \frac{5x}{12}$

She ate the remaining six cookies

Therefore,

$\frac{5x}{12} = 6\\\\5x = 72\\\\x = 14.4$

Thus she made approximately 15 cookies

When a number is added to 1/5 of itself, the result is 24. The equation that models this problem is n+ 1/5+n = 24. What is the

kap26 [50]

Answer:

n = 20

Step-by-step explanation:

If we call "a number" n, the equation modelling that statment is:

$\frac{1}{5}n+n=24$

Now, if we have one whole thing - 5/5 - and add 1/5 of that thing, we'll have a total of 6/5 of it. By that same logic, 1/5 of n + 5/5 of n = 6/5 of n. We can write that fact as

$\frac{6}{5}n=24$

So, we slice this number n up into 5 equal parts, we take 6 of those slices, and that gets us a total value of 24. What would the value of just 1 slice - a single fifth of n - be? Well, we'd just need to divide 24 by 6 to find that

$\frac{1}{5}n=24\div6=4$

And if 1/5 of something is 4, that whole thing, 5/5, must be 5 × 4, or 20! Writing that step out in symbols, we have

$\frac{1}{5} n\times5=4\times5=20=n$

So n = 20.
