Answer:6.6666666667
Step-by-step explanation:just divided it
Hello from MrBillDoesMath!
Answer:
Not so simple. See discussion below
Discussion:
Consider these two examples:
0<= f < = 1, then (2/3) * f < (2/3) * 1 = 2/3
so the product is less than either of the factors
f = -5, then (2/3)* (-5/1) = -10/3
so the product is actually larger than the factor -5 !
In other words, the general answer depends upon the sign as well as value of the fraction. The problem probably meant that multiplying a positive fraction by a number less than 1 and >= 0 makes the product smaller. But as your see from the above examples, a more fine grained analysis is required for a full answer.
Thank you,

Answer: the store charged $40 for the bike helmet before tax.
Step-by-step explanation:
Let x represent the amount that the store charge for the bike helmet before tax.
If the sales tax rate was 8%, it means that the amount of tax that was charge is
8/100 × x = 0.08 × x = 0.08x
Monica paid sales tax of $3.20 when she bought a new bike helmet. This means that
0.08x = 3.2
Dividing the left hand side and the right hand side of the equation by 0.08, it becomes
0.08x/0.08 = 3.2/0.08
x = 40
