Learners work out percentage increase, percentage reduction, and percentage change by comparing starting and ending values. The questions cover savings growth over a year, price reductions during a sale, test score changes over two weeks, weekly distance changes, calorie decreases in a recipe, and rainfall changes between months. Worked solutions show the subtraction, division, and conversion to percentages.",{"@graph":14,"@context":73},[15,34,56],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/document/","Document",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/document/exam/","Exam",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/document/percentage-change-word-problems-1-work-out-the-percentage-change/637436/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":49,"encodingFormat":47,"isAccessibleForFree":50,"interactionStatistic":51},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/percentage-change-word-problems-1-work-out-the-percentage-change/637436.png","ImageObject",300,407,{"name":42,"@type":43},"A glass of water","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-10-30","2026-10-22",true,{"@type":52,"interactionType":53,"userInteractionCount":55},"InteractionCounter",{"@type":54},"ViewAction",7,{"@type":57,"mainEntity":58},"FAQPage",[59,65,69],{"name":60,"@type":61,"acceptedAnswer":62},"How do you find a percentage increase from a starting and ending value?","Question",{"text":63,"@type":64},"Subtract the starting value from the ending value, divide by the starting value, then multiply by 100.
