Hello there! To solve types of questions like these, we can write and solve a proportion. We are looking for the percentage of 380 out of 863.6. Let's set up the proportion like this: 380/863.6 = x/100. Cross multiply the values in order to get 38,000 = 863.6x. Now, divide each side by 863.6 to isolate the "x". 38,000/863.6 is 44.00185271 or 44 when rounded to the nearest whole number. 380 is appox. 44% of 863.6.
Answer:
The numbers are 5 and 20 respectively.
Step-by-step explanation:
Let two numbers are x and y.
According to question-
x + y = 25...............................(i)
Given x is smaller number and y is larger number.
then,
2 y - 3 x = 25..........................(ii)
To solve equation (i) and (ii)-
Firstly multiply by 3 in equation (i) and then add in equation (ii)-
<em> 3 x + 3 y = 75</em>
<em><u>- 3 x + 2 y = 25</u></em>
<em><u>5 y = 100</u></em>
<em>y = 20</em>
Put y = 100 in equation (i)-
We get,
<em>x = 25 - 20</em>
<em>x = 5</em>
<em>Therefore x = 5 and y = 20 .</em>
