Question

afla numerele care lipsesc (48+?) :8= 9 ( ? - 35 ): 5= 10. ( 92 - ? ): 6 = 3 ( ? + 199) : 10 = 20

Answer 1

(48+?) : 8 = 9 
48+? = 9*8
48+? = 72
? = 72-48
? = 24

(?-35):5 = 10
?-35 = 5*10
?-35 = 50
? = 50+35
? = 85

(92-?):6 = 3
92-? = 6*3
92-? = 18
?=92-18
?=74

(?+199):10 = 20
?+199= 10*20
?+199 = 200
?= 200-199
?=1

Answer 2

9x8=72; 72-48=24, deci (48+24):8=9
10x5=50, 50+35=85, deci (85-35):5=10
6x3=18, 92-18=74, deci (92-74):6=3
20x10=200, 200-199=1, deci(1+199):10=20
