Answer: He works 16 hours a day
Explanation:
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
121×43=?
For fraction multiplication, multiply the numerators and then multiply the denominators to get
12×41×3=483
Since 48 divided by 3 equals 16 then,
483=16
Therefore:
121÷34=16
Solution by Formulas
Apply the fractions formula for division, to
121÷34
and solve
12×41×3
=483
=16
Therefore:
121÷34=16
