Mrshape:

Answer without detail workings will not be accepted because it seems many of us know the answer but don't understand how they got the answer

0.25*100=25
0.4*100=40
25=5*5
40=2³*5
lcm=2³*5²
lcm=200
200/100=2

Next question loading
This will be the last question for today this week has not be easy for me.
Let me sleep a bite I have a class by 10.30

sorry

Spartancosta:
sorry

Thanks

I will update tomorrow

Mrshape:
Question 55 What is the sum of one exterior angle and it's interior angle in a 50-gon

180

Mrshape:
Question 55 What is the sum of one exterior angle and it's interior angle in a 50-gon

180 degrees (50-2)× 180/50 + 360/50 = 180

Mrshape:
Question 55 What is the sum of one exterior angle and it's interior angle in a 50-gon

180-360 180*50-360 9000-360=8640 one interior angle=8640/50 172.8 total exterior angle=360 one exterior angle=360/50=7.2 interior +exterior=172.8+7.2=180

I would have posted the answer earlier if only i had typed the answer without showing the calculation

Mrshape:

Show workings

0.25 = 25/100 = 1/4

0.4 = 4/10 = 2/5

1/4, 2/5


LCD is obviously 20.. i can't express myself beyond this using my phone's keyboard.

0.4 as a fraction= 4/10

0.25 as a fraction = 25/100

their denominators : 10, 100


multiples of 10= 2, and 5

multiples of 100= 2,5,10,25,and 50

common multiples : 2, and 5

so the least is 2

ans = 2
