Mr townsend needs to make 13 pairs of butterfly for customers for a play. Each pair of wings is made with 3/4 yard of fabric. The fabric costs $8 per yard.
You’ll apply properties of multiplication in the following steps to find the total cost of fabric.
1. Use multiplication to write an expression for the amount of fabric needed to make 13 pairs of wings.
2. Multiply the amount of fabric by the price per yard to find an expression for the total costs.
3. Use the associative and commutative properties to rearrange the terms in the expression to make it easier to calculate. Explain why the rearranged expression is easier to work with.
4. Simplify your expression to find the total costs. show your work

Michaela needs to represent this statement as an inequality.
One-fourth of a number is no more than two-thirds.
Drag and drop a symbol to correctly complete the inequality.
Answer: the third option
Step-by-step explanation:
The third option means less than or equal to, so if 1/4 of a number is no more than 2/3, it is less than or equal to 2/3
The correct symbol for the inequality is ≤
What is an inequality?An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.
Given that, Michaela needs to represent this statement as an inequality.
One-fourth of a number is no more than two-thirds.
So, in the given options, the third option means less than or equal to,
so if 1/4 of a number is no more than 2/3, it is less than or equal to 2/3
Hence, the inequality will be =
x/4 ≤ 2/3
Hence, the correct symbol for the inequality is ≤
