To divide real numbers as fractions multiply by the of the divisor?
" ... multiply by the RECIPROCAL of the divisor.
How are equivalent fractions related to simplifying fractions?
When a fraction is simplified, it is made into an equivalent fraction with no common divisor between the numerator and denominator.
Is a fraction never a rational number?
Fractions where both the numerator and divisor are rational numbers are always rational numbers.
When doing fractions why is it easier to multiply and divide fractions than add and substract fractions?
It is easier to multiply or divide fractions than to add or subtract fractions because in multiplication, you just have to multiply the numerator by the numerator and the denominator by the denominator. Same applies with division of fractions, except that you have to reciprocate the fraction you're dividing with (divisor) then proceed to multiplication. Whereas, in addition and subtraction of fractions, you still have to get their Least Common Denominator (LCD).
What math process uses reciprocals?
When you divide fractions you need to multiply by the reciprocal of the divisor. You would also use it anytime the multiplicative inverse is required.
