Question

The Primrose Nursery makes a wildflower seed mix by mixing 10 different wildflower seeds together.

The line plot shows the number of pounds of each type of seed that it uses.

Line plot shows number line from three-eighths to one and quarter. The number line is divided into 7 equal parts. 1 dot on three-eighths, 2 dots on five-eighths, 3 dots on three-fourths, 1 dot on seven-eighths, 1 dot on one and one-eight and 2 dots on one and quarter are given.

Part A
Drag the numbers to complete the expression that represents the total number of pounds of seed the nursery uses in all.
Numbers may be used once, more than once, or not at all.

Answer 1

`\text{Total Number of Pounds = }8(3)/(8)$ pounds`

Explanation:

The line plot shows the following information.

• 1 dot on three-eighths,
• 2 dots on five-eighths,
• 3 dots on three-fourths,
• 1 dot on seven-eighths,
• 1 dot on one and one-eight; and
• 2 dots on one and quarter .

To determine the total number of pounds of seed the nursery uses in all, we have:

`\left((3)/(8)X1\right) +\left((5)/(8)X2\right)+\left((3)/(4)X3\right)+\left((7)/(8)X1\right)+\left(1(1)/(8)X1\right)+\left(1(1)/(4)X2\right)`

`=\left((3)/(8)\right) +\left((5)/(4)\right)+\left((9)/(4)\right)+\left((7)/(8)\right)+\left((9)/(8)\right)+\left((5)/(2)\right)\\=(67)/(8)\\\\$Total Number of Pounds = 8(3)/(8)$ pounds`
