1. what is the result of subtracting $\frac{7}{8}$ from $3\frac{1}{8}$?

a. $2\frac{1}{8}$
b. $2\frac{2}{8}$
c. $3\frac{4}{8}$
d. $3\frac{6}{8}$

1. which number is equivalent to $4\frac{7}{18}-3\frac{9}{18}$?

a. $\frac{1}{18}$
b. $\frac{16}{18}$
c. $1\frac{8}{18}$
d. $1\frac{1}{2}$

Explanation:

Step1: Calculate total tomato plants

$7 \times 15 = 105$

Step2: Calculate total sweet corn plants

$8 \times 17 = 136$

Step3: Find difference for Part A

$136 - 105 = 31$

Step4: Calculate corn ears for Part B

$136 \times 6 = 816$

Step5: Calculate kids per cabin (Q15)

$45 \div 5 = 9$

Step6: Subtract fractions for Q16

First rewrite $3\frac{1}{8}$ as $\frac{25}{8}$. Then $\frac{25}{8} - \frac{7}{8} = \frac{18}{8} = 2\frac{2}{8} = 2\frac{1}{4}$

Step7: Subtract mixed numbers for Q17

Rewrite $4\frac{7}{18}$ as $\frac{79}{18}$ and $3\frac{9}{18}$ as $\frac{63}{18}$. Then $\frac{79}{18} - \frac{63}{18} = \frac{16}{18} = \frac{8}{9}$

Answer:

1. Part A: 31 more sweet corn plants

Part B: 816 ears of corn

1. 9 kids
2. B. $2\frac{1}{4}$
3. B. $\frac{8}{9}$
