Question

sendo x = 2/3:5/3-13/5: 0,52 e y = 0.88... : 0,66... + 1/3:5/9 , escreva o número x/y na forma fracionária.

Answer 1

x = 6/15 - 13/5 : 52/100
x = 6/15 - 1300/260
x = 6/15 - 65/13
x = 78/195 - 975/195
x = -897/195 = -4,6

y = 88/100 : 66/100 + 9/15
y = 8800/6600 + 9/15
y = 44/33 + 9/15
y = 220/165 + 99/165 
y = 319/165 = 1,9333...
