Katie said, '' negative numbers are integers.'' what was her error?

Answers

An integer is defined as whole number, or a number that is not a fraction. Any whole number that is negative or positive can be an integer. Technically, not all negative numbers are integers. If the number is not a whole number, it is not considered an integer. For example, -2.5 is not an integer.

Her error was that an integer is not just negative numbers, integers are whole numbers that are not fractions, which mean it could be positive or negative whole numbers.

erika has 3 pieces of ribbon. each piece is 25 yards long she needs to cut pieces that are 22 inches long . what is the greatest number of 22-inch pieces that she can cut from the three ribbons ?

Answers

Answer: 120 pieces.

Step-by-step explanation:

We know that 1 yard = 36 inches

Given: The length of each piece of ribbon= 25 yards $=25*36=900\text{ inches}$

If she needs to cut 22 inches long pieces, then the total number of pieces cut from 1 ribbon $=(900)/(22)=40.0909\approx40\text{ pieces}$

Thus, the total number of pieces she cut from 3 ribbons $=3*40=120\text{ pieces}$

Hence, the greatest number of 22-inch pieces that she can cut from the three ribbons =120

Well 1 yard is 36 inches so 25 yards is 900 and then divide the 900 by 22 which equals 40.9090 but you have to put this down to 40 and because you have 3 ribbons it's 40 x 3 = 120!
