GRADE 5 TEXAS Multiplication and Division WORKSHEETS
Multi-digit multiplication Multiplying lage numbes is a pocess of multiple steps. Fist, you multiply: 542 6 =,252 2 You have now used up all you ones. Coss out the 6 in the ones place and place a zeo in the next column to show this. Now you multiply: 542 20 = 0,840 5 4 2 2 6 2 2 5 2 + 0 8 4 0 4, 0 9 2 Add up you wok:,252 + 0,840 = 4,092 Use a calculato to help you wok out the values you could expect when multiplying the following. Check the columns: a a one by a one 9 7 b a ten by a one 4 5 c a hunded by a one 26 7 d a ten by a ten 72 e a ten by a hunded 55 20 T TH TH H T O 2 2 would give me a one only.

Divisibility ules Divisibility ules tell us if a numbe can be divided evenly by anothe (that is, with no emaindes). Use the ules to test out the numbes in the last column. The fist two have been done fo you: Divisible by Rule Test 2 4 5 A numbe is divisible by 2 if it s even (ends in 0, 2, 4, 6, o 8). A numbe is divisible by if the sum of its digits is divisible by. A numbe is divisible by 4 if the numbe made by the last 2 digits is divisible by 4. A numbe is divisible by 5 if thee s a 0 o 5 in the ones place. Is 458 divisible by 2? Yes, because it ends in an even numbe. Is 7,28 divisible by? 7 + 2 + 8 + = 8 Yes, because 8 is divisible by. Is,92 divisible by 4? Is 455 divisible by 5? 6 9 0 A numbe is divisible by 6 if it is divisible by 2 AND. A numbe is divisible by 9 if the sum of its digits is divisible by 9. A numbe is divisible by 0 if thee is a zeo in the ones place. Is 74,60 divisible by 6? Is it divisible by 2? Is it also divisible by? Is 6,45 divisible by 9? Is 5,680 divisible by 0?

Division In division, we use ou knowledge of multiplication to help us. We can split 96 into 900 + 0 + 6. 900 divided by is 00, so we put a in the hundeds place. 2 0 divided by is 0, so we put a in the tens place. 9 6 6 divided by is 2, so we put a 2 in the ones place. 96 = 2 Divide these numbes: a b c 4 8 4 5 5 5 9 d e f 9 9 9 0 4 4 8 4 6 6 6 6 g h i 9 9 9 2 4 6 2 6 9 Sometimes it s easie to split the numbes diffeently. We can also split 96 into 900 + 6. 900 divided by is 00, so we put a in the 9 2 6 hundeds place 6 divided by is 2. We put the in the tens place and the 2 in the ones place. 96 = 2 In these poblems, if thee ae no tens in a numbe we put a 0 in to show this and also to hold the place of the othe numbes! 2 Decide how you ll split these numbes and then divide.

Division with emaindes Sometimes numbes don t divide evenly. The amount left ove is called the emainde. Look at 527 divided by 5. 500 divided by 5 is 00. 0 5 2 27 divided by 5 is 5 with 2 left ove (this is the emainde). 5 5 2 7 This can be witten as 2. 527 5 = 05 2. Divide these 2 digit numbes. Each poblem will have a emainde. a b c 9 7 5 4 4 7 6 8 d e f 5 6 4 4 9 6 6 2 2 Divide these digit numbes. Each poblem will have a emainde. a b c 5 5 5 7 6 6 4 4 8 d e f 9 9 9 4 4 8 4 5 6 6 8 Solve these poblems: a Giovanni s gandma has given him a bag of gold coins to shae among himself and his two sistes.

Division with emaindes Thee ae ways of expessing emaindes. How we do it depends on how we d deal with the poblem in the eal wold. Look at: 0 5 2 5 5 2 7 4 One way is to wite 2 as in the example above. We use this when we don t cae about being absolutely pecise and when the emainde can t be easily boken up. An example would be shaing 527 jelly beans among 5 people. Solve these poblems expessing the emaindes as. a Shae 26 blue pencils among 4 people. b Shae 25 pape clips among 7 people. 5 We can also expess a emainde as a faction. We do this when we can easily shae the emainde. Fo example, 9 cakes shaed among people is 6 and one thid each. Solve these poblems expessing the emainde as a faction: 6 9 a Shae pizzas among 4 people. b Shae 50 sandwiches among people. 6 We expess emaindes as decimals when we must be absolutely pecise. Shaing dolla amounts is a good example of this. We add the cents afte the decimal point to help us. Ty these: a Shae 2 dollas among 4 people. b Shae 27 dollas between 2 people. 27 divided by 2 is. Now we have one dolla left. How how many cents is half of one dolla? 4 2 0 0 2 2 7 0 0 Copyight P Leaning Gade Gade 5 5 MULTIPLICATION AND AND DIVISION DIVISION 5.NBT.5, 5.C 5.NBT.6 7
