Today, let me introduce to you on the remainder concept type 1, this is actually the easiest type if you compare to the other two types in the remainder concept. So, after writing so much, let us watch a short video on how to solve the questions on the remainder concept type 1 usingbranching method, which I feel is the quickest and the fastest method you can use. (If this is not very clear, please go to: https://www.youtube.com/watch?v=gHmMF63D6WE, I'm sorry for any inconvenience.)
After finishing watching this video, do you understand? Can you apply this method to other similar type of questions? If you answered both or either one of the questions- "NO!", then you better watch this video again to make this clear before starting the next lesson. After watching this video for a few times and you still don't understand, please ask me! Goodbye and you better know how to do this type of concept. 1. Remainder Concepts Mr Tan had a sum of money. He donated $1400 to a charity and spent $400 on some Christmas presents. He then gave 2/5 of the remainder to his 3 children. Given that each child received 1/12 of Mr Tan's original sum of money, how much did each child receive? 2. Repeated Identity Concept Andy, Beckham, Chris and Daniel shared $168. Daniel received 1/7 of the total amount of money received by Andy, Beckham and Chris. Andy received 3/4 of the total amount of money received by Beckham and Chris. Beckham received 2/5 as much money as Chris. How much did Berkham receive? 3. Equal Concept A box contained some pencils and pens. 20% of the pencils and 3/5 of the pens were removed. In the end, there were half as many pencils as pens. Given that there were 30 more pens than pencils at first, find the number of pencils in the box at first. 4. External Transfer With Unchanged Quantity Concept In November, Mrs Tan spent 80% of her monthly salary. In December, her monthly salary increased by $900 and he saved 15% of her new monthly salary. Given that she saved the same amount of money in these two months, what was her monthly salary in December? 5. Internal Transfer With Unchanged Total Concept
John. Matt and Luke put in their money together to buy a toy. John paid 1/3 of the total amount paid by Matt and Luke. Matt paid 1/5 of the total amount paid by John and Luke. If Luke paid $60 more than Matt, how much did the toy cost? ![]() Today, I am going to teach you how to do a typical remainder concept word problem in a primary 5-6 Question. So here the question goes: Joanne gave 1/5 of his monthly salary to his mother. She gave 3/4 of the remainder to her father and saved the rest each month. She managed to save $400 every month. How much did she earn a month? Adapted from: http://www.teach-kids-math-by-model-method.com/remainder-concept.html |
