Ally collects stickers as a hobby. She gives her sisters of her stickers.

sertanlavr [38]

Answer:

$\frac{16}{25}$

Step-by-step explanation:

Ally gives her sister = 1/5 stickers

Ally gives her cousin = 1/5 of the remainder stickers

Assume Number of sticker Ali has = 1

Remainder after giving stickers to her sister = 1 - 1/5 = 4/5

Number of stickers she gave her sister = $\frac{1}{5}\times\frac{4}{5}$

= $\frac{4}{25}$

Sticker she has = $1-\frac{1}{5}-\frac{4}{25}$

= $\frac{25-5-4}{25}$

= $\frac{16}{25}$

Sticker left with Ally is equal to $\frac{16}{25}$ .

I don't quite understand the LCD and the unlike denominators properly. May someone explain it, please.

Whitepunk [10]

Hey!

----------------------------------------------------------------------

LCD stands for Lowest Common Denominator.

----------------------------------------------------------------------

Explanation:

So let's say we have the equation 1/9 * 16/27

We want to find the LCD of both fractions. To find the LCD of both fractions find a the lowest common denominator in both fractions.

In this equation the lowest common denominator is 27 because 9 can go in 27 and 27 can go into itself. Se basically 27 is the lowest possibly common denominator both fractions can get to.

-18+-6 please help

Verdich [7]

Answer:

-24

Step-by-step explanation:

If you are struggling with this here's a tip!

-18+-6 is what you are trying to solve

The 6 is negative, so get rid of the plus sign -18-6

2 negative numbers are just added like positive numbers

So add 18 and 6, you should get 24

Don't forget about the negative!
