First calculate how many students are in each class. The first class has 3 rows of 7 students and 3 x 7 = 21. The second class has 4 rows of 5 students and 4 x 5 = 20. Then add both totals to calculate the total number of students outside; 21 + 20 = 41.
Correct answer: 29g
Rhoda has 15g of water and when she adds 14g she will have 29g
15g+14g=29g
Correct answer: Each shows a different fraction because they both have 3 shaded sections but a different number of total sections.
The model for the first fraction is divided into 6 equal parts. We shade 3_6 to show the same amount as 1_2. The model for the second fraction is divided into 8 equal parts. We shade 3_ 8 that it shows this two model are different fractions.
Correct answer: 21 𝑐𝑚²
3 X 7 = 21
Correct answer: 400
Option (B) is correct. In order to solve for the unknown number in an addition problem, subtract the smaller number from the bigger number. 756 – 356 = 400.

Correct answer: 44g
Cristine has 11g of water. If she needs 4 times that amount, we can multiply to find the answer.
11 x 4 = 44g
Correct answer: 2/8 is equal to 4/16.
The model for the first fraction is divided into 8 equal parts. We shade 2/8 to show the same amount as 1/4. The model for the second fraction is divided into 16 equal parts. We shade 4/16 to show the same amount as 1/4.
