The lines in a 2 cup liquid measuring cup divide each cup into eights. if you measure 1 3/4 cups of water, betwern which two quantities can you be certain that your exact measurment will be?

between 1 5/8 and 1 7/8 cups
between 1 1/2 and 1 3/4 cups
between 1 1/2 and 2 cups
between 1 3/8 and 1 5/8 cups

between 1 1/2 and 2 cups

Step-by-step explanation:

The size of the container is 2 cups and its divided by 8 lines, then each line will represent: 2 cups/ 8 lines= 1/4 cup per line.

Since the water is exactly at 1 3/4 cup you can't say for sure if it's above or less than 1 3/4.  We need to estimate it at bigger picture, use the other lines that on the top and the bottom of 1 3/4 line.  

The lines below will be: 1 3/4 - 1/4          = 1 1/2

The line above 1 3/4 will be: 1 3/4 + 1/4   = 2  

We can certainly say that the water is between 1 1/2 and 2 cups

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
