Make the whole number a fraction by making it ?/1
Make the mixed number a improper fraction by multiplying the denominator by the whole number and then adding the numerator and putting that on top of the original denominator.
SOLVE using basic multiplying fractions rules
Fractions and decimals are usually rational numbers. Besides, multiplying rational and irrational numbers is also similar.
Dividing by a non-zero rational number is the same as multiplying by its reciprocal.
It the two rational numbers have different signs, then the answer will be negative, otherwise it will be positive.
did you get this off of big ideas learning
Dividing by a rational number (other than zero) is simply multiplication by its reciprocal.
Yes, but only if the rational number is non-zero.
The algorithm is A/B * C/D = AB/CD.
A rational number can be stated in the form a/b where and b are integers. Adding or multiplying such numbers always gives another number that can be expressed in this form also. So it is also rational.
The product of two rational numbers, X and Y, is smaller than either of them if both are between 0 and 1.
If 0.75 is the radius, that's rational. If 0.75 is the diameter, the radius is also rational: multiplying two rational numbers together always gives you a rational number.
p/q * r/s = (p*r)/(q*s)
It the signs of the two numbers that you are multiplying or dividing is the same, then the answer is positive, otherwise the answer is negative. Remember though, that division by 0 is not defined.
