Now, there’s a second part to the question, which we’ll take a look at now. Okay, great! So, we’ve rearranged the formula to make □ the subject. So, this is gonna give us □ is equal to nine □ over five plus 32. And we know that because earlier on when we expanded our parentheses, we did five multiplied by 32, which gave us 160. And that’s because if we divide 160 by five, we get 32. So, first of all, we’re gonna have nine □ over five. So, to enable us to do that, what we can do is divide through by five. And then, as we want to make □ the subject to the formula, we want a single □ on its own. And when we do that, what we get is nine □ plus 160 is equal to five □. So then, next, what we do is add 160 to each side of the equation. And when we do that, what we’re gonna get is nine □ equals, and then we got five multiplied by □, which is five □, and five multiplied by 32, which is 160. So, now, what’s the next step? Well, now, what we’re going to do is expand our parentheses. So, when we do that, what we have is nine □ equals five then multiplied by □ minus 32. So, the first step in rearranging to make □ the subject is to multiply each side of the equation by nine because that’s gonna remove the fraction on the right-hand side. This is an old way or an old term that’s used to describe the same thing. It is worth noting though that you might sometimes hear degrees Celsius as degrees centigrade. So, what we have is our formula, which is □ equals five multiplied by □ minus 32 over nine, where □ is the temperature in degrees Celsius and □ is the temperature in degrees Fahrenheit. Rearrange the formula to make □ the subject. The formula for converting degrees Fahrenheit to degrees Celsius is □ equals five multiplied by □ minus 32 over nine.
