dodinh88 · Answer

Đáp án:

Giải thích các bước giải:

a) `x/100 = 0,02`

`=> x = 0,02 × 100`

`=> x = 2`

b) `3/(x/1000) = 0,05`

`=> x/1000 = 3 : 0,05`

`=> x/1000 = 60`

`=> x = 60 × 1000`

`=> x = 6000`

Study well

Đáp án:

a)x= 2

b)x= 6000

Giải thích các bước giải:

a) $x 100 = 0, 02 " role="presentation" style="margin: 0px; padding: 1px 0px; display: inline-block; line-height: 0; text-indent: 0px; text-align: left; text-transform: none; font-style: normal; font-weight: normal; font-size: 18.15px; letter-spacing: normal; word-wrap: normal; word-spacing: normal; white-space: nowrap; float: none; direction: ltr; max-width: none; max-height: none; min-width: 0px; min-height: 0px; border: 0px; position: relative;" tabindex="0"> x 100 = 0, 02 x100=0,02$

$\Rightarrow x = 0, 02 \times 100 " role="presentation" style="margin: 0px; padding: 1px 0px; display: inline-block; line-height: 0; text-indent: 0px; text-align: left; text-transform: none; font-style: normal; font-weight: normal; font-size: 18.15px; letter-spacing: normal; word-wrap: normal; word-spacing: normal; white-space: nowrap; float: none; direction: ltr; max-width: none; max-height: none; min-width: 0px; min-height: 0px; border: 0px; position: relative;" tabindex="0"> \Rightarrow x = 0, 02 \times 100 \Rightarrowx=0,02\times100$

b) $3 x 1000 = 0, 05 " role="presentation" style="margin: 0px; padding: 1px 0px; display: inline-block; line-height: 0; text-indent: 0px; text-align: left; text-transform: none; font-style: normal; font-weight: normal; font-size: 18.15px; letter-spacing: normal; word-wrap: normal; word-spacing: normal; white-space: nowrap; float: none; direction: ltr; max-width: none; max-height: none; min-width: 0px; min-height: 0px; border: 0px; position: relative;" tabindex="0"> 3 x 1000 = 0, 05 3x1000=0,05$
