What are the fraction &amp; percent equivalent to the decimal below check all that apply

Salutations!

<span>What are the fraction & percent equivalent to the decimal below

To convert decimal into fraction, you need to multiply the number according to the decimal point. For instance, 0.2. As you see, after the decimal point, there is only on number. Therefore, we will be dividing it by 10. 0.2 into a decimal is 2/10

0.24 converted into a fraction = 24/100

To convert decimal into percentage, you need to just multiply the number by 100 as percentage means out of 100, and just add  the symbol (%).

0.24 converted into a percentage = 24%

Thus, your answer is option B and E.

Hope I helped (:

10. MJ and Peter Parker leave school traveling in opposite
Paladinen [302]

Using proportions, it is found that:

  • Peter is walking at a rate of 3 km/h.
  • MJ is biking at a rate of 9 km/h.

---------------------------

  • Peter is walking at a rate of x km/h.
  • MJ is biking 6 km/h faster than Peter, thus 6 + x km/h.
  • Opposite directions, thus, their distance increases at a rate of (6 + 2x) km each hour, as 6 + x + x = 6 + 2x.

6 + 2x km each hour, 18 km after 1.5 hours, thus, the rule of three is:

1h - (6 + 2x) km

1.5h - 18 km

Applying cross multiplication:

1.5(6 + 2x) = 18

9 + 3x = 18

3x = 9

x = \frac{9}{3}

x = 3

x + 6 = 3 + 6 = 9

Then:

  • Peter is walking at a rate of 3 km/h.
  • MJ is biking at a rate of 9 km/h.
