A classroom has 26 chairs and 16 computers. What is the ratio of computers to chairs?
Anna71 [15]

**THE PERSON UNDER ME IS ALSO CORRECT, THIS IS JUST ANOTHER WAY TO APPROACH RATIOS**

Explanation: Ratio seldom compares two numbers by dividing them (this depends on the problem). We are given A 16 computers and B 26 chairs. Therefore we have the formula of A/B.For example 16/26


Solving: Divide A by B: 16/26= 0.615 or 0.6

Multiple: Multiple the quotient by 100 in order to get the percentages. 0.615 x 100 = 61.5% (if you rounded 0.61, the answer would be 60%; for this problem I didnt round hence, 61.5%)


Answer: 61.5 %

Side note: I hope this helps, feel free to let me

know if you have anymore questions.

Find the solution of the system of equations.<br> 2y = 9<br> -6x + 4y = -46
Anvisha [2.4K]

Answer:

x = 32/3 , y = 9/2

Step-by-step explanation:

2y = 9

-6x + 4y = -46

y = 9/2

-6x + 4*(9/2) = - 46

- 6x +18 = - 46

- 6x = - 64

x = 64/6 = 32/3
