Increasing pattern sizes

I have a pattern in a book wich says it’s 70% of actual size. Does anyone know what figure I should use on a photocopier to increase the pattern to 100%. I just can’t get my head round this one. Thanks Marg. x

I think you need 1.43 or 143% - if Ive worked it out right!

I’d agree with that too x

Thanks for that Roz, I’ll give it a try, I just could not figure it out and I am usually good with percentages and fractions. Marg. x
