To find the product of expression $\frac{9}{10}\times 50$

Answer to Problem 9PSQ

45

Explanation of Solution

Given information:

Expression $\frac{9}{10}\times 50$

Formula / Concept Used: Factorization

Calculation:

To find the product, break all numbers into its factors and then cancel out the same numerator & denominator. So here -

  $\frac{9}{10}\times 50=\frac{9}{10}\times 5\times 10$

Writing 50 as product of its factors. Since 10 is in both numerator & denominator, it cancels out,

  $\frac{9}{10}\times 5\times 10=9\times 5=45$

Conclusion-
