Question

Out of 64 residents of Math City, $\frac{5}{8}$ of residents went to picnic. How many residents did not go?

• A. $5$
• B. $40$
• C. $24$

Answer 1

The correct option is C $24$

Total number of residents in the Math City = 64

Total number of residents who went for picnic $=\frac{5}{8}$ × total number of residents

$=\frac{5}{8}\text{of}64$

$=\frac{5}{8}\times 64=\frac{5}{8}\times \frac{64}{1}$

$=\frac{5}{8}\times \frac{8\times 8}{1}=\frac{40}{1}$

Number of residents went for picnic = 40
Hence, Number of residents did not go for picnic $=64-40=24$
