because if we take the one out and the zero it will just be 2/3

You can divide 21 by 30 and that would give you 0.7 and if you divide 2 by 3 that would give you 0.6 repeating. Therefore, that is how I know that 21/30 is greater than 2/3.

A number is divided by 4, and then the quotient is added to 17. The result is 25. Find the number
PolarNik [594]
Hello!!!

So we are given some number, which we will call x for simplicity purposes. They tell us that number is divided by 4 so x/4, and then 17 is added, so we now have x/4+17 and they tell us this combination is equal to 25 so set what we have so far equal to 25. So we have finally x/4+17=25. Now we just solve for x!

x/4+17=25 first we subtract 17 from both sides leaving us with, x/4=8 so now See need to multiply by 4 on both sides to clear the fraction and get x alone. So we have now

x=8*4 so x=32

Now we can check our answer by putting our value of x into equation and make sure it’s true. So we have for our check,

32/4+17=25 and 32/4 is 8 so we have 8+17=25 which is 25=25 so our equation is true and our answer is correct!!

Hope this helps you understand the concept!! Any questions please just ask!! Thank you so much!!
