Answer:
36⁄125 or if we are talking about the lowest term it is 9
/3125
Step-by-step explanation:
Step 1: 0.288 = 288⁄1000
Step 2: Simplify 288⁄1000 = 36⁄125 Percent" or "%" means "out of 100" or "per 100",
<em>Or for the lowest term:</em>
Therefore 0.288% can be written as
0.288
100
.
Next, we can multiply by
1
in the form of
1000
1000
to eliminate the decimal in the numerator:

.
We can now reduce the fraction as:
288

Answer:the total cost of the collar is $5.11
Step-by-step explanation:
To make a collar for her dog, she needs to buy some chain,a clasp, and a name tag.
The length of the chain that she wants to buy is 40 centimeters.
1000 centimeters = 1 meter
40 centimeters = 40/1000 = 0.04 meters.
One meter of chain costs $9.75. Therefore, 0.04 meters of chain would cost
0.04 × 9.75 = $0.39
The clasp is $1.29 and the name tag is $3.43. Therefore, the total cost of the collar would be
0.39 + 1.29 + 3.43 = $5.11
