The example will equal x to the power of 6. 34.A ratio as a fraction: You can express particular numbers in the ratio as fractions by finding what the whole ratio adds up to and using that as the denominator. e.g. 3/5 is the first part of the ratio 3:2 35.Arc: An arc is a section of the circumference of a circle IGCSE Maths英语数学词汇知识点总结(配图)
