Answer:
$2.25
Step-by-step explanation:
Divide the cost ($18) by the amount of flowers (8.)
We need to evaluate the value of fraction
.
We also given j=12.
In order to evaluate the value of fraction
, we need to plug j=12.
Plugging j=12, we get

We have 12 in numerator and 4 in denominator.
We always divide top number by bottom number.
So, we need to divide 12 by 4.
On dividing 12 by 4 we get 3.
<h3>Therefore,

</h3>
3
To calculate a fraction of a quantity, multiply the quantity by the numerator of the fraction and divide by the denominator
of 20 = (3 × 20 )/4 =
= 15
of 20 = (3 × 20 )/5 =
= 12
