It’s going to be A. She was supposed to use distributive property
Answer: 3/4
Step-by-step explanation: Dividing by a fraction is the same as multiplying by its reciprocal. In other words, we can change the divison sign to multiplication and flip the second fraction.
So here, 3/8 divided by 1/2 can be rewritten as 3/8 × 2/1.
Now we are simply multiplying fractions so we multiply across the numerators and we multiply across the denominators.
So we have 3 × 2 which is 6 and 8 × 1 which is 8. Since 6/8 is not in lowest terms, we divide the numerator and the denominator by the greatest common factor of 6 and 8 which is 2 and we get the equivalent fraction 3/4.
Therefore, 3/8 divided by 1/2 is 3/4.
F^-1(x) is the inverse so...
f^-1(x) = (-1/5)x - 11/5
So you would just have to divide 20/7 to get the percentage of it.
The answer would be 2.85%.
X+7<23
x<23-7
x<16
So, all numbers from zero to 15
Those are 16 positive integers
