With what in regard? For fractions, percentage is relative to the amount “full”. Think or a bottle of water, if it’s 50% full, it’s got 1/2 (50/100) filled with water. Simplifying is the process of taking a big fraction, say, 12/36, and finding the similarity to reduce it. 12 and 36 are both even, so let’s try to divide it by 2. 12/2 is 6, and 36/2 is 18. 6/18. However this is simplified it is not in simplest form, so we can divide It again. 6/2 is 3, and 18/2 9. 3/9 can be reduced by 3, making 1/3. 1/3 is the simplest form.
Answer:
First & Third options
Step-by-step explanation:

If the width is 3 on each side, that is 3 + 3 = 6.
26 - 6 = 20.
There are two sides left: 20 divided by 2 = 10.
10+10+3+3 = 26.
The length is 10.
Answer: 98
Step-by-step explanation:
First find the mean of the numbers you currently have.
93 + 95 + 89 + 95 + 100
and divide by 5 to get 94.4.
Now you need to find the extra number.
The number has to be higher than 94. I know there is an easier way, but I started by adding 100 and kept going down til I was at 98.
93 + 95 + 89 + 95 + 100 + 98
divided by 6 is 95
Area of triangle = 1/2 (base) (height)
120 = 1/2 (base) (15)
240 = 15 base
Base = 240 ÷ 15
Base = 16 inches
Answer:16 inches
