No, you can't. If the denominator is greater than the numerator, that fraction's absolute value is always less than 1. If the numerator is greater than the denominator, that fraction's absolute value is always more than 1. Therefore, for both of them to be equal to each other, you are saying that a fraction that is less than 1 is equal to the fraction more than one. However, you can have a fraction with a larger denominator actually be of greater value than the one with the larger numerator. For example, -(9/8) vs -(8/9). -(9/8) has a greater numerator, yet -(8/9) is greater than it, despite having a larger denominator. Of course, this case can be written off as having the negative factored in with either the numerator with denominator, so it is easier to remember the rule above without the negative mumbo jumbo.
Let us set up the equation using the given information
Boys = x
Girls = √x
Boys + girls = 42
Equation: x + √x = 42
You can now work out this equation to solve for x, OR reason your way through it. By substituting numbers into the equation. Try 36
36 + √36 = 42
36 + 6 = 42
42 = 42
ANSWER: 36 Boys (and 6 girls)
Hope this helps! God bless!! :)
So in your calculator you put 2 divided by 5. You will get 0.4 you don’t need to round anything because the decimal doesn’t repeat. The answer is 0.4
Step-by-step explanation:
5x+y=7
20x+2=y
put y value in first equation
5x+(20x+2)=7
25x=5
x=5
now put x value to determine y
as we know 20x+2=y
20(5)+2=y
y=102
