Hi everyone, so we want to solve the equation a plus 5 eighth equals one half, and then we want to check our answer.
00:15
So let's start, in order to solve this equation, let's start by making both fractions have the same denominator.
00:22
So we're going to pick eight because that's the easy one.
00:26
So in order to make one half into eights, we're going to multiply the top and the bottom of the by 4 because 2 times 4 is equal to 8 so we just need to do the numerator really which is equal to 4 8s so now it's a lot easier to solve our equation right because now we have a plus 5 8s equals 4 8s so now all we need to do is subtract 5 8s from both sides and over here i'm going to add negative 5 8s instead subtract just because i don't have room over here.
01:10
And then that'll give us our answer in the form of, let's see, negative 5.
01:15
Negative 5 .8s plus 5 .8s is going to cancel out.
01:18
So then we have just a on the left hand side like we wanted.
01:22
And then we're going to subtract 5 eighths from 4 eighths.
01:25
So when we're going to do that, just it's going to be something over 8, right? because we have the same denominator on the fractions.
01:32
Like that's why we simplified earlier.
01:34
So then just 4 minus 5 is negative 1...
