The document provides sixteen specific arithmetic problems designed to reinforce students' understanding of basic multiplication principles involving multiples of ten, such as 20, 40, 50, and 100. By identifying the unknown numbers in equations like 'x times 50 equals 8000', students practice fundamental algebraic thinking and place value concepts. The worksheet includes an answer key at the bottom, making it an excellent resource for independent student practice, classroom assessments, or home learning. The exercises are structured to gradually increase in complexity, ensuring a comprehensive review of multiplication skills and improving the speed and accuracy of mathematical operations for elementary school learners.",{"@graph":14,"@context":72},[15,34,55],{"@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/grade-4-multiply-by-whole-tens-missing-factor-worksheet/548503/",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/grade-4-multiply-by-whole-tens-missing-factor-worksheet/548503.png","ImageObject",300,407,{"name":42,"@type":43},"Kyle","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-11-08","2026-10-12",true,{"@type":52,"interactionType":53,"userInteractionCount":33},"InteractionCounter",{"@type":54},"ViewAction",{"@type":56,"mainEntity":57},"FAQPage",[58,64,68],{"name":59,"@type":60,"acceptedAnswer":61},"What
