Answer:
Explanation:
57÷27=?
Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.
Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes
57×72=?
For fraction multiplication, multiply the numerators and then multiply the denominators to get
5×77×2=3514
This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 35 and 14 using
GCF(35,14) = 7
35÷714÷7=52
The fraction
52
is the same as
5÷2
Convert to a mixed number using
long division for 5 ÷ 2 = 2R1, so
52=212
Therefore:
57÷27=21/2
