There were 62 females and 217 males present at the high school pep rally. Express as a simplified ratio.

4.5

Step-by-step explanation:

the ratio is 62:217

so we add the ratio

62+217=279 so we divide it by 62 because we are looking for the females so 279÷62

4 1\2 that is in decimal point 4.5 pls follow me thanks

This is a half life problem.
you'll find this page quite but i'll solve your question anyway.
time = half-life * log [bgng amt / ending amt] / log 2
time = 5,600 * log [100 / 15] / log 2
time = 5,600 * 0.82390874095 / 0.30102999566
time = 5,600 * 2.7369655942
time = 15,327 years
