Dan and Alan take turns mowing the grass of a yard that is 2400 square yards in area. Dan takes an hour to mow the whole lawn using his old mower. Alan only takes 40 minutes to mow the whole lawn using his new mower. As you answer the following questions, don't forget to show your units!

A. How much lawn does Dan mow in a minute?

B. How much lawn does Alan mow in a minute?

B. How many more square yards does Alan mow in a minute than Dan?

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.

1.0

d

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.

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
