Answer:

Step-by-step explanation:

1/8 = 1/9 + x ...multiply by LCD of 72

9 = 8 + 72x

9 - 8 = 72x

1 = 72x

1/72 = x

1/8 = 1/10 + x....multiply by 40

5 = 4 + 40x

5 - 4 = 40x

1 = 40x

1/40 = x

1/8 = 1/11 + x....multiply by 88

11 = 8 + 88x

11 - 8 = 88x

3 = 88x

3/88 = x

can all unit fractions be made in more then 1 way like this ?

not to sure because that last one....because it has been that a unit fraction is the outcome of adding together 2 unit fractions...but that last one...3/88 is not a unit fraction

Lelechka [254]

The complete question in the attached figure

Let
x-----------------> number of paintbrushes----------- > $0.95 each
y---------------- > number of jar of paint-------------- > $0.99 each

we know that
0.95x+0.99y = $4.87

using a graph tool

the solution will be a pair of coordinates that are whole numbers -- > see the attached figure

the solution is the point (2,3)

x=2---------------------- > number of paintbrushes
y=3---------------------- > number of jar of paint

the answer is
number of paintbrushes=2
number of jar of paint=3
