The class has 28 student. One group has four more students so surat 4 from 28. 28-4=24 since one of the groups have twice as many students as the other divide 24 by 3. 24 / 3 = 8. It says 1 group has for more than twice the other group so that would mean 2/3 of 24 and 4 would be the answer 16+4=20. The first group had 8 students, the other group has 20 students.

What is 5/16 written as a percent?
Rom4ik [11]
First, you divide the fraction, and then you multiply it by 100.
So you get:
\frac{5}{16} * 100
0.3125 * 100
31.25

So, 5/16 is 31.25% 

Hope this Helps! :)

Solve the inequality and show your solution on a number line: −4x≥−1
kiruha [24]

<em>*To solve an inequality, it's the same as solving an equation; isolate the variable to one side.</em>

For this, all you need to do is divide both sides by -4. And since we are dividing by a <u>negative</u>, flip the inequality sign and your inequality is x\leq\frac{1}{4}

Now to graph this. Since x can be "equal to" 1/4 ( ≤ = less than or equal to), you will have a <u>closed circle on 1/4.</u> And since x can also be "less than" 1/4, <u>the arrow will be going to the left of 1/4.</u>
