Understand the context: Understand the context of the problem.We have two fractions representing the time it took for two different seeds to sprout: cress seed took 78 of a week, and artichoke seed took 717 weeks. We want to know what question the division of these two fractions answers.
Perform the division: Perform the division of the two fractions.To divide fractions, we multiply the first fraction by the reciprocal of the second fraction.(78)÷(717)=(78)×(177)
Simplify the expression: Simplify the expression.We can simplify the expression by canceling out the common factors in the numerator and the denominator.(78)×(177)=178
Interpret the result: Interpret the result.The result of the division, 178, represents how many times the cress seed's sprouting time fits into the artichoke seed's sprouting time. Therefore, it answers the question of how many times as long the artichoke seed took to sprout as the cress seed.
