The solution is, the value of r is 8.
Simplify simply means to make it simple. In mathematics, simply or simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.
here, we get,
given that,
the expression is,
3 1/2r = 28
now, we have to solve the expression to get the value of 'r'.
we get,
3 1/2r=28
7/2r=28
r=(28/1)(2/7)
r=4 × 2
r = 8
Hence, The solution is, the value of r is 8.
