12x=180
divide both sides by 12
x=15
if their is 10 girls, then you need 5 more to keep the ratio.
Answer:
<h2>1. (52 - 2) (1 + 1) = 100</h2><h2>2. (12 - 2) (9 + 1) = 100</h2><h2>3. (6 - 2) (24 + 1) = 100</h2><h2>4. (3 - 2) (99 + 1) = 100</h2><h2>5. (102 - 2) (0 + 1) = 100</h2>Step-by-step explanation:
<h3>1. let r= 52 and s= 1</h3><h3>(52 - 2) (1 + 1) = 100</h3><h3>50 × 2 = 100</h3><h3 /><h3>2. let r= 12 and s= 9</h3><h3>(12 - 2) (9 + 1) = 100</h3><h3>10 × 10 = 100</h3><h3 /><h3>3. let r= 6 and s= 24</h3><h3>(6 - 2) (24 + 1) = 100</h3><h3>4 × 25 = 100</h3><h3 /><h3>4. let r= 3 and s= 99</h3><h3>(3 - 2) (99 + 1) = 100</h3><h3>1 × 100 = 100</h3><h3 /><h3>5. let r= 102 and s= 0</h3><h3>(102 - 2) (0 + 1) = 100</h3><h3>100 × 1 = 100</h3>
