Question

Por favor es urgente tengo poco tiempo

Answer 1

a. 
a = 8k, b = 2k, 
8k - 2k = 15   
6k = 15 
k = 15 / 6
k = 5 / 2

a = 8(5 / 2) 
a = 4(5)
a = 20
b = 2(5 / 2)
b = 5

a = 20
b = 5

b.
c = 4k, d = 3k
4k - 3k = 2
k = 2

c = 4(2)
c = 8
d = 3(2)
d = 6

c = 8
d = 6

c.
x = 11k, y = 44k
11k - 44k = 15
- 33k = 15
- k = 15 / 33
- k = 5 / 11
k = - 5 / 11

x = 11(- 5 / 11)
x = - 5
y = 44(- 5 / 11)
y = 4(- 5)
y = - 20

x = - 5
y = - 20

d.
m = 6k, n = 4k
6k - 4k = 20
2k = 20
k = 20 / 2
k = 10

m = 6(10)
m = 60
n = 4(10)
n = 40

m = 60
n = 40

e.
f = 15k, e = 12k
12k + 15k = 18
27k = 18
k = 18 / 27
k = 2 / 3

f = 15(2 / 3)
f = 5(2)
f = 10
e = 12(2 / 3)
e = 4(2)
e = 8

f = 10
e = 8
