How can you subtract fractions with unlike denominators?

Rama09 [41]

Answer:

No, You can't. You have to make their denominators equal!

$-\frac{7}{10}$

Step-by-step explanation:

So first, you make their denominators equal!

$\frac{1*2}{5*2} =\frac{2}{10}=\frac{1}{5}$

Multiplying both the numerator and denominator with the same number results in the same fraction, just un-simplified

So, we input it!

$\frac{2}{10} -\frac{9}{10} = -\frac{7}{10}$

There you go!

Hope you get better at math!(gets wayyyyyyyyyyy...y more complicated later)

Hope this helps!

See Ya!

One day, a sprinter runs the 100 m dash 24 times, for a total distance of 24 00 m. how many kilometers did the sprinter run?

tigry1 [53]

The total distance that was covered by the sprinter in Kilometers is:

2.4 Km

<h3>How much is the total distance covered?</h3>

To obtain the total distance covered by the sprinter, we need to first realize that 1 Km is equal to 1000 meters. That said, the question above requires us to change 2400 meters to kilometers.

Thus we will have:

2400 Meters * 1 km / 1000 meters

= 2.4 km

So, the total distance covered by the sprinter in kilometers is 2.4
