Answer-

$-70\%$

Solution-

The given data as follows,

$-70\%,\ 0.34,\ -\dfrac{2}{5},\ 0.96\%$

After converting all the percentages and fractions to decimal, we can compare them all.

For converting percentages to decimal to divide the number by 100, so

$-70\%=\dfrac{-70}{100}=-0.70,\\\\0.96\%=\dfrac{0.96}{100} =0.0096$

Then converting the fraction into decimal,

$-\dfrac{2}{5}=-\dfrac{2\times 20}{5\times 20}=-\dfrac{40}{100}=-0.40$

As, all the numbers are converted into decimal, now comparing all the numbers,

$-0.70$

$-70\%$

0.6(4-2x)=20.5-(3x+10)

solong [7]

The solution of 0.6(4-2x)=20.5-(3x+10) is x = 4.5

Solution:

Given, expression is 0.6 ( 4 – 2x ) = 20.5 – ( 3x + 10 )

We have to solve the above given equation for x.

Now, take the equation

$\rightarrow 0.6(4-2 x)=20.5-(3 x+10)$

We have to use BODMAS rule. BODMAS means sequence of operations which is brackets, order, division, multiplication, addition and then subtraction

On solving the brackets, we get

$\rightarrow 0.6 \times 4-0.6 \times 2 x=20.5-3 x-10$

Now multiplication is given preference

$\rightarrow 2.4-1.2 x=10.5-3 x$

$\rightarrow 3 x-1.2 x=10.5-2.4$

Now subtraction is done

$\rightarrow 1.8 \mathrm{x}=8.1$

Now division is performed

$\rightarrow x=\frac{8.1}{1.8}=4.5$

Hence, the value of x is 4.5
