Answer:
12% of the sixth graders are left handed.
Step-by-step explanation:
There are 150 students in total. Out of those 150, 18 are left handed.
Step 1: We make the assumption that 150 is 100% since it is our output value.
Step 2: We next represent the value we seek with x.
Step 3: From step 1, it follows that 100% = 150
Step 4: In the same vein, x% = 18.
Step 5: This gives us a pair of simple equations:
100%=150(1)
x%=18(2)
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
100%/x% = 150/18
Step 7: Taking the inverse (or reciprocal) of both sides yields
x%/100% = 18/150
x = 12%
Therefore, 18 is 12% of 150 :)
