It highlights common examiner concerns: missing or unclear calculation steps, incorrect values losing marks, and the importance of writing exact calculator inputs. The material includes discovery activities, an example on increasing an item’s cost by 20%, guidance for interpreting results like 100 ÷ 1.2, and “top tips” using decimal-percent equivalence. It also provides scaffolded and numberless problem-solving practice, including a 25% change cars scenario.",{"@graph":69,"@context":122},[70,84,105],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":20,"@type":76,"position":81},"https://docshare.wps.com/document/exam/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/teaching-the-fundamentals-level-2-original-value-after-percentage-change/620975/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":99,"encodingFormat":97,"isAccessibleForFree":100,"interactionStatistic":101},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/teaching-the-fundamentals-level-2-original-value-after-percentage-change/620975.png","ImageObject",300,407,{"name":92,"@type":93},"Margaret","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-11-08","2026-10-20",true,{"@type":102,"interactionType":103,"userInteractionCount":19},"InteractionCounter",{"@type":104},"ViewAction",{"@type":106,"mainEntity":107},"FAQPage",[108,114,118],{"name":109,"@type":110,"acceptedAnswer":111},"Why are original value after percentage change questions often poorly answered?","Question",{"text":112,"@type":113},"They are often not answered with the required process.
