The big keyword here is the word RATIO. Ratio of what? The ratio of girls to boys in the entire grade. A ratio is just the two amounts divided by each other (you can also call it the slope, but ignore that if that makes it more confusing).
(81 girls)/(72 boys)
Simplify it by breaking it up a bit.
81 = 9 * 9
72 = 9 * 8
Cross out similar terms to gain the result of:
What they want from us is the ratio of girls if a group has 16 boys. So set it up like this:
Just by looking at this you may be able to solve for "x" if you have a good understanding of fractions, but instead let's do the long way.
First off is to get "x" alone by multiplying 16 boys on both sides.
x =
Remember that:
16 = 8*2
x =
Cancel out the like terms (8) to give you:
x = 18 girls

Step-by-step explanation:
a =
b =
c =
<u><em>Finding a*b:</em></u>
a*b =( )*(
)
= (3.47*4.61) * ()
When bases are same, powers are to be added
= 15.997 *
= 15.997 *
= 159.97
Rounding it off
=> 1.60 * 10²
<u><em>Finding a/b:</em></u>
=>
Using rule of exponents
=> 0.753 *
=>
=>
=> 7.53 * 10⁻¹⁴
<u><em>Finding c/a:</em></u>
=>
=> 1.59 *
=> 1.59 * 10¹³
