Question

află numerele necunoscute.
a)x+1325=13352
b)100×b=100100
c)y-15256=91049
d)248007-z=42315
e)y:1000=450
f)10000:z=10

Answer 1

Răspuns:

a)x+1325=13352=>x=13352-1325=>x=12027

b)100×b=100100=>b=100100:100=>b=1001

c)y-15256=91049=>y=91049+15256=>y=106305

d)248007-z=42315=>z=248007-42315=>z=205692

e)y:1000=450=>y=450·1000=450000

f)10000:z=10=>z=10000:10=>z=1000

Answer 2

Răspuns:

Explicație pas cu pas:

a)

x + 1325 = 13352

x = 13352 - 1325

x = 12000

b)

100 × b = 100100

b = 100100 : 100

b = 1001

c)

y - 15256 = 91049

y = 91049 + 15256

y = 106305

d)

248007 - z = 42315

z = 248007 - 42315

z = 2 20569

e)

y : 1000 = 450

y = 450 x 1000

y = 450000

f)

10000 : z = 10

z = 10000 : 10

z = 1000
