⓵ You need to calculate what 30% of 40 students represents. In order to do that, I like to change the pourcentage number into a decimal number because I find it easier to use.
30% = 30 ÷ 100 = 0.3
Now that you have your decimal number, you need to multiply 0.3 by 40 to find out the number of students that 30% represents :
0.3 × 40 = 12
Which means that 12 students out of 40 chose soccer!
⓶ You now need to calculate what ⅕ of 40 students represents. Again, in order to do that, I like to change the fraction into a decimal number because I find it easier to use.
⅕ = 1 ÷ 5 = 0.2
Now that you have your decimal number, you need to multiply 0.2 by 40 to find out the number of students that ⅕ represents :
0.2 × 40 = 8
Which means that 8 students out of 40 chose football!
⓷ Now all you have left to do is subtract the number of students who chose football from the number of students who chose soccer :
12 - 8 = 4
So to answer your question : "How many more students chose soccer than football?"
→ There are 4 more students who chose soccer rather than football!
I really hope this helps, if there’s anything just let me know! ☻
