20% as a fraction is 1/5
25% is 1/4
40% is 2/5
and 70% is 7/10
Depending on what your fraction is, you can find the answer in the fraction itself-
20%, you can take 20, 5 times to get to 100. Hence 1/5.
25 can go into 100 4 times (1/4)
40 is just 20 twice, so its 2/5.
Take 10 7 times and get 7/10.
Hope this helps a bit :)
If Nico gave away some red circles and you would like to know how many red circles does he have left, you can calculate this using the following step:
Nico has 15 red circles.
n ... the number of red circles that he gave away
15 - n ... the number of circles that Nico still has
The correct result would be 15 - n.
Answer:
r=2q-6
Step-by-step explanation:
10q-5r=30
Subtract 10q from both sides:
-5r=30-10q
Divide both sides by -5:
r=2q-6
Hope this helps!
The correct answer for this is 9/2.
