Solve for r <br> r/8 =7<br> r = ____

Nostrana [21]

Answer:

r=56

Step-by-step explanation:

Since, r divided by 8 gives 7, if you do the inverse function(which is basically like the reverse of the question)

you can multiply 8 and 7 to find the r.

So 8 times 7 gives 56.

And to check you can do

$\frac{56}{8}$ which gives 7

You can tell me if my explanation is wrong. Thanks
