Answer:
2/3
Step-by-step explanation:
Glenn needs to cut pieces of ribbon that are each 1 meter long to make ribbon key chains. If he has 6 pieces of ribbon that are each 1 dekameter long, how many 1−meter pieces of ribbon can he cut?
1 decametre = 10 metres
Hence,
10 meters = 6 pieces of ribbon
1 meter = x pieces
Cross Multiply
10x = 6
x = 6/10
x = 2/3 (1 meter pieces of ribbon)

Your answer should be 5.75225876
Answer: 75%
We know that 1/4 of 24 (25%) is 6, 6 fits into 18 three times and 25 times 3 is 75. So the answer is 75%
Answer:
<u>The correct answer is A. 1/8</u>
Step-by-step explanation:
<u>Let's solve (1/3 * 9/16) / 1 1/2 = x</u>
(1/3 * 9/16) / 1 1/2 = x
9/48 / 1 1/2 = 9/48 * 2/3 = 18/144
18/144, we can simplify dividing by 18 at the numerator and the denominator, this way:
x = 18 ÷ 18/ 144 * 18 = 1/8
<u>The correct answer is A. 1/8</u>
I believe the X numbers are divided by 2, to get the Y numbers. So the blank X box is 1 and the other is 12.
