Answer:
<em>8cm</em>
Step-by-step explanation:
Given three pieces of string of length 16 cm, 56 cm and 24 cm respectively. To get the the greatest length that each piece of string can be if she wants to cut the three lengths of string into smaller pieces such that all the pieces are of equal length, with no string left over, we will have to find the greatest common factor for the three lengths
16 = 2 * 8
56 = 7 * 8
24 = 3 * 8
Since 8 is common to all the factors, hence the greatest common factor is 8.
<em>Hence the greatest length that each piece of string can be, in cm is 8cm</em>
Here is the completed table:
Has pet Has no pet Total
7th grade 102 48 150
8th grade 107 68 175
Total 209 116 325
<h3>What is a two-way table?</h3>
A two way table is used to show the frequency of two categorical variables. Information are usually presented in rows and columns.
- The 7th grade students that have no pets = 150 - 102 = 48
- The 8th grade students that have pets = 175 - 68 = 107
- Total students that have pets = 102 + 107 = 209
- Total students that have no pets = 48 + 68 = 116
- Total = 209 + 116 = 325
