Question

16. Află numărul necunoscut:
91: x= 31
25 ml : a = 5 ml
71xx = 421
8lxa = 561
38 ml + x = 60 ml
931 + x = 1001
425 ml - x =137 ml
x - 75 ml = 125 ml
​

Answer 1

Răspuns:

91:x=31

x= 91:31

x= 2,93

a= 5

x=421:7

x= 60,14

a=561:8

a= 70,125

x=60-38

x=22 ml

x=1001 - 931

x= 70

x=425 - 137

x= 288

x=125 + 75

x= 200 ml
