Question

Bài 2: Tìm x, biết:

a) x + 15,96 = 1,345 x 13

b) 99,99 – x = 5,678

c) x x 5 = 105,85

d) x : 8,9 = 9,8

e) 76,32 : x = 36

Answer 1

a, x + 15,96 = 17,485

x = 17,485 - 15,96 = 1,525

b, 99,99 - x = 5, 678

x = 99,99 - 5,678 = 94,312

c, x = 105,85 : 5 = 21,17

d, x = 9,8 x 8,9 = 87,22

e, x = 76,32 : 36 = 2,12

Answer 2

Bài 2: Tìm x, biết:

a) x + 15,96 = 1,345 x 13

x + 15,96 = 17,485 

x = 17,485 - 15,96

x = 1.525

b) 99,99 – x = 5,678

x = 99,99 – 5,678

x = 94.312

c) x x 5 = 105,85

x = 105,85 : 5

x = 21.17

d) x : 8,9 = 9,8

x = 9,8 x 8,9

x = 87.22

e) 76,32 : x = 36

x = 76,32 :  36

x = 2.12

Answer 3

a,x=(1,345.13)-15,96=1,525

b, x=99,99-6,678=93,312

c,x=105,85:5=21,17

d, x=9,8x8,9=87,22

e, x=76,32:36=2,12
