Question

Ex 6,Pls tot,am sa am la test semestrial,coroana e a voastră dacă îmi ziceți

Answer 1

Răspuns:

a/b=6 => a=6b

a)

a+b/b = 6b+b/b = 7b/b = 7

b)

a+b/a = 6b+b/6b = 7b/6b = 7/6

c)

b/a+b = b/6b+b = b/7b = 1/7

d)

a-b/b = 6b-b/b = 5b/b = 5

e)

a-b/a = 6b-b/6b = 5b/6b = 5/6

f)

a/a-b = 6b/6b-b = 6b/5b = 6/5

g)

a+b/a-b = 6b+b/6b-b = 7b/5b = 7/5

h)

2a+5b/5b = 12b+5b/5b = 17b/5b = 17/5

i)

3a+4b/5b = 18b+4b/5b = 22b/5b = 22/5

j)

8a-3b/5b = 48b-3b/5b = 45b/5b = 45/5 = 9
