Question

20% of 260 students at hill middle school ride a bus to school. how many students ride a bus to school?

Answer 1

Answer:

52 students ride a bus to school

Step-by-step explanation:

Step 1: Our output value is 260.

Step 2: We represent the unknown value with x.

Step 3:  From step 1 above $260 = 100%.

Step 4: Similarly, x = 20%.

Step 5: This results in a pair of simple equations:

260 = 100%(1).

x = 20%(2).

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

$\frac{260}{x}$ = $\frac{100}{20}$%

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{260}$ = $\frac{20}{100}$

⇒x=52$

Therefore, 20% of 260 is 52.

Hope this helps! :)
