Which equation represents this number sentence? three less than one-fifth of a number is 28. (3−15)n=28 (15−3)n=28 15n−3=28 3−15n=28

Hey there!

I believe there's a typo here that makes 1/5 look like 15. If not, none of them are correct.

Assuming 15 is 1/5..

Let's start with our keywords:

Is means equals. (i.e he is good means he = good).

Of means multiplication (1/5 of 20 is 1/5 times 20 with is 20/5 is four).

This means that when reading this question, we have three less than whatever is next. 3 will be subtracted from the value listed next.

This value is 1/5 of a number. This means that we're multiplying 1/5 times this number, which we can call n.

We have to remember we are subtracting three and it all equals 28, which gives us:

1/5n - 3 = 28

Your answer is the 3rd option.

Hope this helps!
