Answer:
40%
Step-by-step explanation:
If there are 1200 students in the school and 720 of them are boys that means 480 of them are girls.
I like to do cross multiply and divide so the equation for that would be 480/120 = ?/100
if you cross and multiply 480 by 100 you will get 48000 then if you divide that by 1200 you will get 40 as your missing value.
Im basically just saying 480/1200 = 40%
If you need further help there are plenty of you tube videos on how to cross multiply and divide
Hope this helps

<h2>it will take 30 minutes</h2>
Step-by-step explanation:
obtain a formula
<h3>=> M = $0.10($p)+$25</h3>
<u>insert the value of p dollars</u>
<h3>=> M = $0.10(50) + 25</h3>
<u>multiply 50 by 0.10</u>
<h3>=> M = $5 + 25</h3>
<em> </em><u>add 25 + 5</u>
<h3><em><u>=></u></em> M = $30</h3>
<u>So it takes 30 minutes for international minutes</u> <em><u>Thank </u></em><em><u>You</u></em>
