Eureka Math Grade 5 Module 6 Lesson 25 Homework Answer Key
Question 1.
Fred and Ethyl had 132 flowers altogether at first. After Fred sold \(\frac{1}{2}\) of his flowers and Ethyl sold 48 of her flowers, they had the same number of flowers left. How many flowers did each of them have at first?
Answer:
Total number of flowers = 132
Number of flowers with Fred = x
Number of flowers with Ethyl = 132 – x
Number of flowers sold by Fred = \(\frac{1}{2}\) x = \(\frac{x}{2}\)
Number of flowers sold by Ethyl = 48
Number of flowers remaining with Fred = x – \(\frac{x}{2}\) = \(\frac{x}{2}\)
Number of Flowers remaining with Ethyl = 132 – x – 48 = 84 – x
Number of flowers remaining with Fred = ethyl
\(\frac{x}{2}\) = 84 – x
x + \(\frac{x}{2}\) = 84
\(\frac{3x}{2}\) = 84
3x = 168
x = 56 .
Number of flowers with Fred = x = 56
Number of flowers with Ethyl = 132 – x = 132 – 56 = 79 .
