1) Change 7/2 to a mixed or whole number?
answer: 3 1/2
2) Multiply 4/5 * 20. Write your answer in simplest form.
right on 1.
On the second, change it to
4/5 * 20/1 Does that help?
also: 4*20 / 5
To change 7/2 to a mixed or whole number, you need to divide the numerator (7) by the denominator (2). The quotient (result of the division) will be the whole number part of the mixed number, and the remainder will be the numerator of the fraction part.
In this case, when you divide 7 by 2, the quotient is 3 and the remainder is 1. So the mixed number is 3 1/2.
To multiply 4/5 by 20 and write the answer in simplest form, you simply multiply the numerator (4) by 20 and keep the denominator (5) the same.
4/5 * 20 = (4*20) / 5 = 80/5
To simplify the fraction, you need to find the greatest common factor (GCF) of the numerator and denominator. In this case, both 80 and 5 have a common factor of 5.
Divide both the numerator and denominator by the GCF (5) to get the simplified fraction:
80/5 = (80/5) / (5/5) = 16/1 = 16
So the answer, in simplest form, is 16.
