Tricia had 4 1/8 yards of fabric to make curtains. When she finished she had 2 3/8 yards of fabric left. She said she used 2 2/8 yards of fabric for the curtains. Do you agree?

Answers

Well for this you have to do 4 1/8 - 2 3/8. You cannot subtract 1 - 3, so you have to take away 1 from three and add 8 to 1 so now the equation is 3 9/8 - 2 3/8. This is equal to 1 6/8 or 1 3/4, so no, she did not use 2 2/8 yards of fabric.

No because if you add up the fabric she 'used' and the fabric she made to make the curtains it doesn't match up with the original yards of fabric she had to make the curtains.

2 3/8+ 2 2/8= 4 5/8

4 5/8 is the supposedly original fabric she had. It's only 1/2 off from the original fabric of yards.

So no I don't agree.

Daniel is three years older than twice his brother's age. Daniel is 17. Fill in the box with the expression that represents the age of Daniel's brother. Let b represent Daniel's brother's age.

Answers

Daniel's age is X
Daniel's brother age is Y

X = 3 + ( 2Y )

Y = ( X - 3 ) / 2

In case of Daniel is 17

then his brother's age is = ( 17 - 3 ) / 2 = 7 years

How many times greater is the value of 6 in 640,700 than the value of the 4 in 67,040?

Answers

Answer:

15000 times greater is the value of 6 in 640,700 than the value of the 4 in 67,040.

Step-by-step explanation:

Given : 640,700 and 67,040.

To find : How many times greater is the value of 6 in 640,700 than the value of the 4 in 67,040.

Solution : We have given 640,700 and 67,040.

In 640,700

in this 6 is at hundred thousand place = 600,000

In 67,040

Here 4 is at ten place = 40 .

We can write 600,000 = 15000 * 40.

So, We can say 600,000 is 15000 times the 40.

Therefore, 15000 times greater is the value of 6 in 640,700 than the value of the 4 in 67,040.

Well the 6 is in the One-Hundred Thousand place while the 4 is in the Tens place.

So it would be 100x greater
