# need help with gcse maths please! watch

1. So this is probably a really simple question but I just don't understand it haha: what is 0.12 as a fraction of 0.8? It's non-calculator by the way.

Also this one: The base of a pyramid has n sides. Circle the expression for the number of sides on the pyramid: 2n or n-1 or n or n+1.

Thanks!

Have you done any working out for question 1? Ill start you off.
Spoiler:
Show

Start off by knowing 0.8 is 100%.( As this is the output of your question)
x is the value you need to establish

100%=0.8 x=0.12- output value= x%-0.12

Formula then becomes 100%=0.8 and x%=0.12

Now please to attempt to do the rest and do let us know if you do not understand. Thanks.
