This is a formula chart to help(i would’ve given you the answer but you didn’t give the sharp)
Answer:
r=0.5
Step-by-step explanation:
0.125r+0.25r-0.0625=0.25+r
0.375r-0.0625=0.25+r
0.375r-r=0.25+0.0625
-0.625r=0.3125
r=0.3125/0.625
r=0.5

the answer is 2. because you need to subtract the fractions once you do that you’ll get -2 • (-1) then multiple you’ll have 2 .
