All rows contain the same number of plants. There are between 5 and 12 plants in each row. How many plants are in each row?<\/p>\n<p>Answer: 7 plants.<\/p>\n<p>Explanation: There are 28 tomato plants in a row. To find out how many plants in a row we will find the factors of 28 i.e 1,2,4,7,14,28. As there are between 5 and 12 plants 7 is the only number between 5 and 12. So 7 plants are planted in each row.<\/p>\n<p>Question 14.<br \/>\nElla bought some key chains and spent a total of $24. Each key chain costs the same whole-dollar amount. She bought between 7 and 11 key chains. How many key chains did Ella buy?<\/p>\n<p>Answer: 8<\/p>\n<p>Explanation: Ella spent a total of $24. To find how many key chains first we will find the factors of 24. Factors of 24 are<br \/>\n1,2,3,4,6,8,12,24. As Ella bought between 7 and 11 key chains 8 is the only number between 7 and 11. So 8 key chains Ella bought.<\/p>\n<p>Question 15.<br \/>\nSandy has 16 roses, 8 daisies, and 32 tulips. She wants to arrange all the flowers in the bouquets. Each bouquet has the same number of flowers and the same type of flower. What is the greatest number of flowers that could be in a bouquet?<\/p>\n<p>Answer: 2 roses, 1 daisy, and 4 tulips in 8 bouquets.<\/p>\n<p>Explanation: First we must add all the flowers i.e 16+8+32= 56, Now we can divide 56 flowers equally in each bouquet. Like 2 roses, 1 daisy and 4 tulips in 8 bouquets or 8 roses in 2 bouquets, 8 daisies in 1 bouquet and 8 tulips in 4 bouquets.<\/p>\n<p>Question 16.<br \/>\nAmir arranged 9 photos on a bulletin board.

How many different rectangles could she make with the 15 tiles? Write a list or draw a picture to show the number and dimensions of the rectangles she could make.<\/p>\n<p>Answer: 2<\/p>\n<p>Explanation: one by 15 tiles and second by 3tiles in a row.<\/p>\n<p>Question 21.<br \/>\nPart Cs<br \/>\nElina\u2019s friend Luke said that he could make more rectangles with 24 tiles than with Elina\u2019s 10 tiles. Do you agree with Luke? Explain.<\/p>\n<p>Answer: Yes<\/p>\n<p>Explanation: As 24 has more factors than 10.<\/p>\n<h3><a id=\"Page_No_329\"><\/a>Page No. 329<\/h3>\n<p><strong>Use the model to write an equivalent fraction.<\/strong><\/p>\n<p>Question 1.<br \/>\n<img loading=\"lazy\" src=\"https:\/\/ccssmathanswers.com\/wp-content\/uploads\/2020\/07\/Go-Math-Grade-4-Answer-Key-Chapter-5-Factors-Multiples-and-Patterns-img-34.jpg\" alt=\"Go Math Grade 4 Answer Key Chapter 5 Factors, Multiples, and Patterns img 34\" width=\"219\" height=\"107\" \/><br \/>\n<img loading=\"lazy\" src=\"https:\/\/ccssmathanswers.com\/wp-content\/uploads\/2020\/07\/Go-Math-Grade-4-Answer-Key-Chapter-5-Factors-Multiples-and-Patterns-img-35.jpg\" alt=\"Go Math Grade 4 Answer Key Chapter 5 Factors, Multiples, and Patterns img 35\" width=\"220\" height=\"109\" \/><br \/>\n\\(\\frac{1}{5}\\) = \\(\\frac{\u25a1}{\u25a1}\\)<\/p>\n<p>Answer: 1\/5= 2\/10<\/p>\n<p>Explanation: From the above figure we can see that there are 5 equal parts and in that 1 part is shaded.
