$7.8T=?kg$

The letter T indicates a metric tonne,

One tonne is equivalent to one thousand kilograms,

Therefore, in 7.8 tons there are

1000*7.8 = 7800 kg

$7800$

$\frac{55}{5}\times200\operatorname{kg}=?T$

First, let's get rid of the fraction:

$\frac{55}{5}=11$

Now we have:

$11\times200kg$

Let's calculate and we get:

$2200kg$

Note that we need the answer in tons, so:

$T=1000kg$

$\frac{2200kg}{1000}=2.2T$

2.2

$x_m=?km$

In one kilometer there are 1000 meters,

therefore one meter is one-thousandth of a kilometer.

$\frac{x}{1000}$

$7kg=?gr$

$7000$

$8.6kg=?gr$

$8600$

$3.21kg=?gr$

$3,210$

$387\frac{1}{4}kg=?T$

$0.38725$

$x^2kg=?gr$

$1000x^2$

$\frac{7}{21}\times100gr=?kg$

1/30$\frac{1}{30}$

$x^2\times100kg=?T$

$\frac{x^2}{10}$
