The decimal is $- 1.75$ $-1.75$ .
The percentage is $- 175 %$ $-175%$

Explanation:

To turn this into a decimal, divide $3$ $3$ by $4$ $4$ .

$\frac{3}{4} = 0.75$ $3/4=0.75$

You can also do this by turning the denominator of the fraction to 100:

$\frac{3}{4} \cdot \frac{25}{25} = \frac{75}{100} = 0.75$ $3/4*25/25=75/100=0.75$

Since it is $- 1 \frac{3}{4}$ $-1 3/4$ , the decimal is $- 1.75$ $-1.75$ .

To turn this into a percent, we know $1$ $1$ is $100 %$ $100%$ , and to turn $0.75$ $0.75$ into a percent, multiply by 100 to get the percentage:

$0.75 \cdot 100 = 75 \to 75 %$ $0.75*100=75 ->75%$

The percentage is $- 175 %$ $-175%$ .

As a decimal, is it $- 1.75$ $-1.75$ , and as a percent, it is $- 175 %$ $-175%$ .

Explanation:

To convert $- 1 \frac{3}{4}$ $-1 3/4$ to a decimal, you have to use long division to divide $3$ $3$ into $4$ $4$ :

$m 4 ∣ 0.75 ¯ ¯¯¯¯¯ ¯ 3.00$ $color(white)(m)4|stackrel(0.75)bar3.00$
$. . - 0$ $color(white)(..)-0$
$color(white)(.......)bar3.0$
$color(white)(...)-2.8$
$color(white)(.......)bar0.20$
$color(white)(...)-0.20$
$color(white)(.......)bar0.00$

So $3/4$ as a decimal is $0.75$ . Now we can rewrite the mixed fraction:

$color(white)=-1 3/4$

$=-1 * (1+3/4)$

$= -1*(1+0.75)$

$=-1*1.75$

$=-1.75$

Now, to get the number as a percent, simply multiply by $100%$ :

$-1.75*100%=-175%$
