Answer 1

Explicație pas cu pas:

a) ab/10 + ab/100 =198/100

10ab+ab=198

10×ab+ab×1=198

ab(10+1)=198

ab × 11=198

ab=18 a=1 b=8

b) abc/10 - abc/100=1188/100

10×abc-abc×1=1188

abc(10-1)=1188

abc × 9 =1188

abc=132 a=1 b=3

c) aa/10+aaa/100+aaaa/1000=26568/1000

100×aa+10×aaa+aaaa=26568

aa00+aaa0+aaaa=26568

aa00+

aaa0+

aaaa

------------

26568 a=8
