Sara's teacher has 6 7/8 cups of water. She used 4/8 a cup of water to water the plant on her desk and 3 2/8 cups for some students who were thirsty. How much water does she have left over?

Amount of water left = 25 / 8 cups

Step-by-step explanation:

Given:

Amount of water teacher Sara have = cups = 55 / 8 cups

Amount of water teacher used = 4/8 cups

Amount of water used by student = cups = 26 / 8 cups

Find:

Amount of water left

Computation:

Amount of water left = Amount of water teacher Sara have - [Amount of water teacher used + Amount of water used by student]

Amount of water left = [55/8] - [4/8 + 26/8]

Amount of water left = [55/8] - [30/8]

Amount of water left = [55-30] / 8

Amount of water left = 25 / 8 cups

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
