Dr dylan collects 2 hailstones during a storm. one hailstone weighs 2 3/8 pounds and the other hailstone weighs 1 3/10 pounds. how much heavier is the larger hailstone than the smaller hailstone.

1  3/40 pounds

Step-by-step explanation:

difference in weight

= 2 3/8- 1 3/10

= 19/8-13/10

=(19*5 -13*4)/40

=95-52/40

=43/40

=1  3/40 pounds

1 3/40

Step-by-step explanation:

2 3/8 - 1 3/10

= 2 - 1 3/8 - 3/10

= 1 15-12/40

= 1 3/40

OR

2 3/8 - 1 3/10

Convert the mixed numbers to improper fractions

= 19/8 - 13/10

Find the LCM of the denominators

(LCM = 40)

= 95 - 52 /40

=43/40

= 1 3/40

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
