I would never use the recurring decimal bound, but it's no different to using 7.5 so it's ok to do so.<br /><br />Regarding the £7.49: I Jo Morganhttps://www.blogger.com/profile/11919801458664779971noreply@blogger.comtag:blogger.com,1999:blog-4242439961617529545.post-89639611787418967552019-05-29T10:06:41.949+01:002019-05-29T10:06:41.949+01:00I am confused by the AQA guidance you quoted:
