Step-by-step explanation:
Say you have these 2 fractions
Cross multiply as following;
If in the end, both numerator and denominator are equal, then the fractions are equivalent.
Examples:
Example 1
Cross multiply
They're equivalent.
Example 2
Cross multiply
They're not equivalent.
Answer:
and perpendicular
Step-by-step explanation:
It's important to remember that equations of lines are always set up in the format of .
is the
value,
is the gradient/slope,
is the
value and
is the y-intercept.
Therefore, we must always rearrange our line equations so that is the subject.
In the first question, we are given the equation .
We rearrange to make the subject:
Then, we divide both sides by 6 to have the isolated:
To find a perpendicular slope, we use the negative reciprocal of the original slope. The negative part of that means we negate the value (it becomes inverse) and the reciprocal part means that we flip the fraction.
So here, the slope is .
So, the negative reciprocal of that would be because we inverse the sign (the negative becomes positive) and the fraction is flipped to create
.
So, the perpendicular slope is .
In the second question, we have two equations. They both need to be rearranged to isolate the .
Look at the slopes of the two equations. If you look carefully, you will see that they are inverse of each other (one is positive and one is negative) and if you imagine , the fraction is flipped.
This means that the values are negative reciprocals of each other, meaning the lines are perpendicular.
Answer:
48%
Step-by-step explanation:
This is a very simple problem of finding percentage.
To find percentage of people preferring pizza, we need to divide "number of person who like pizza" by the "total number of person".
So, that's
240/500
And then we need to multiply by 100 and tag a "%" sign at the end. So let's do this:
So 48% of the people chose pizza.
