Answer:
1/10
Step-by-step explanation:
2/5=4/10
4/10-3/10=1/10
Answer:
we express the ratio of pencil to eraser and multiply it by the number of the number of pencils and erasers. 4/5 * x=20 , so x=25, then it implies that there are 5 erasers.
As a number, half-gallon can be represented as 0.5.
In order to answer this question we will define each term:
whole numbers are numbers that can be defined as a <span>number without fractions which are greater or equal than 0. E.g. 2 0 1 5 6 85
</span>
integer numbers are numbers that can be defined as a number without fractions but which can be either equal to 0 or greater and lower than 0
E.g. -9 -68 8 0 59
rational numbers are any number that<span> can be expressed as a fraction p/q of two integers E.g. 0.5 = 1/2 1 = 1/1 1.25 = 5/4
</span>
irrational numbers are those which have an approximate value E.g. pi = 3.14...
√2 = 1.41.....
real numbers are all of the above
From all those kind of choices the most accurate representation is rational numbers.

Answer:
17 ft, 27 ft, 20 ft
Step-by-step explanation:
Let s represent the length of the shortest side. The the longest side is (2s-7) and the third side is (s+3). The perimeter is the sum of the side lengths:
64 = s +(2s -7) +(s +3)
64 = 4s -4 . . . . . . . . . . . collect terms
16 = s -1 . . . . . . . . . . divide by 4
17 = s . . . . . . . . . add 1
2s -7 = 2·17 -7 = 27 . . . . . the length of the longest side
s +3 = 17 +3 = 20 . . . . . . . the length of the third side
The side lengths are 17 feet, 27 feet, and 20 feet.
